"Yes, we have no bananas", is something said by many temperate zone gardeners. Yet it

does not have to be so. Some bananas are hardier than you might think, since gardeners in

the United States can grow many cultivars outdoors with just a little protection. There areseveral bananas that are even cold hardy into and north of USDA Hardiness Zone 7.

Regardless of your climate, you can always enjoy bananas in containers or as tender

perennials. If you crave amazing, tropical, bold-textured foliage and exotic flowers inyour garden (plus perhaps some edible fruit), you should try growing a banana ... you just

might develop a taste for them. We urge our readers to visit the gardens here at Juniper

Level during our Open House Days in order to see our collection ... summer and fall openhouses are when the bananas are at their peak. We hope this article will prompt you to

bring a little tropicality into your garden!

Our focus is bananas that are reliably winter-hardy in Zone 7b (average winter minimumtemperature of 5 degrees F). To this end, we trial as many species and cultivars as

possible, looking for those that prove to be reliable garden candidates.

History and Background of Bananas

Banana "trees" are tropical herbaceous perennials (not real trees) in the family Musaceae,although the game of rearranging plant families continues as we learn more about plant

relationships from DNA testing. The family Musaceae is closely related to other well

known ornamental tropicals such as Bird-of-Paradise (Strelitziaceae), Canna Lily

(Cannaceae), the tropical gingers (Zingiberaceae) and Heliconia (Heliconaceae). Withinthe family Musaceae, there are 3 genera of bananas;Ensete,Musa, andMusella.

Bananas are native to Southeast Asia, China, Madagascar and Africa. Forty million yearsago, bananas were also native to North America as far north as Oregon, so they certainly

should be included in your native plant garden. In the wild, bananas range from low

equatorial elevations to high altitudes in the tropics, where we find the cold tolerantspecies.

Although bananas have been cultivated as a food for 4,000 - 10,000 years in tropicalareas, Europeans were not aware of the fruit until they started exploring the world during

the Age of Discovery in the 1500s. Edible bananas were not introduced to America until

1876 during the Philadelphia World Exposition. Today, there are several hundred

cultivars of edible bananas grown around the world, but since the 1960s, only onecultivar has been used to produce the yellow dessert bananas eaten in the U.S. and

Europe; Musa acuminata 'Cavendish'. The 'Cavendish' banana is a sterile triploid, which

means it produces fruit in the absence of pollination (parthenocarpy) and therefore doesnot have any seeds. Most edible bananas belong to Musa acuminata or Musa balbisiana

(or are hybrids between the two). These hybrids are given the species name Musa

'paradisiaca'.

In addition to the sweet dessert varieties, there are starchy, unsweet cooking bananas that

are used in a manner similar to how Americans use potatoes. These cooking bananas are

sometimes known as plantains and are commonly boiled, baked, or fried. Musa and

Ensete may be eaten in other ways too. The Chinese eat the immature male flower and

many cultures use the rhizomes and the stem as food or animal fodder. Bananas may also

be dried and eaten as a chip or ground into flour. Bananas are the fourth largest fruit cropin the world behind apples, citrus, and grapes and are a staple food in some parts of the

world.

The era of the 'Cavendish' banana may be coming to an end. Over the last few years, a

fungal pathogen called Panama disease (Fusarium oxysporum f. sp. cubense) Tropical

Race 4 has evolved that attacks and kills 'Cavendish' plants. It has wiped out 'Cavendish'in almost all of Asia. There is no known preventative or cure and it spreads extremely

quickly. If the fungus ever reaches Central America, the monoculture 'Cavendish' farms

that supply the U.S. will be decimated. Ironically it was a different race of the same

disease that allowed the 'Cavendish' to become so popular in the first place. 'Cavendish'replaced the sweeter and larger 'Gros Michael' banana in the 1950s which was also wiped

out by a race of Panama disease. There is currently no replacement for the 'Cavendish'

banana that is tolerant of Panama disease and has the all the traits that American

consumers demand. The next best choice is a cultivar called 'Goldfinger' which is not assweet and has a slight tart-apple flavor. However, the best long term solution is not to

replace a single monoculture crop with another monoculture crop, but rather to adopt thesustainable practice of growing and eating multiple cultivars of banana.

Bananas also have non-food uses. Enseteand Musabanana stems and leaves are used for

their fibers. The coarse fibers are called "manilla hemp" and are used to make paper andrope. The fine fibers are used to make high quality cloth called banana cloth. Banana

leaves are waterproof and are often used to wrap food for storage or cooking. The Fehi

group of bananas, grown in Polynesia, are used to make a red dye (that will turn yoururine red if you eat them). Bananas are used by certain cultures to treat medical disorders

such as bronchitis, ulcers, diabetes, hemorrhoids (don't ask me how!), and diarrhea

among other things. Central Americans collect the sap of the red banana and take it as anaphrodisiac, although this may be a "phallacy", while the Hindus regard the plant as a

symbol of fertility and place the leaves and fruits on the doorstep of newlyweds. In the

1960s it was popular to smoke banana peel for its alleged hallucinogenic affects (whatdidn't they smoke back then?) but the original newspaper story (The Berkeley Barb,

March 1967) that reported this fad was a hoax that fooled the nation.

Bananas are such an important and profitable food crop that the companies that producethem (primarily United Fruit Company, known today as Chiquita and the Standard Fruit

Company, known today as Dole) have grown extremely powerful. Their influence on

Central American politics has lead to the term "Banana Republic" (coined by the authorO. Henry in his 1904 book Cabbages and Kings) which is a pejorative term for a small,

unstable, country run by wealthy, corrupt elites who support the exploitation of people

and land for cheap banana production by taking bribes and kickbacks from the bananacompanies. Hmmm... large companies influencing public policy. Good thing that could

never happen in the US.

Banana Taxonomy

Depending on who you ask, the genus Musa contains 42-60 species while Ensete contains6-8 species. The genus Musella is monotypic (has only one species).Musella lasiocarpa

had been bounced around between Musa and Ensete before getting its own genus in the

1970s. The taxonomy of the family is poorly resolved due to its worldwide cultivationand hybridization by humans over the last 4000+ years. Only 12 species (with a few

dozen cultivars) of Musaceae are cold tolerant enough to be used in temperate gardens.

Our choices here in the US are limited, but there are some beautiful options to choosefrom.

Banana Genetics

Banana genetics are complex and quite interesting (if you are a banana nerd). Plants in

genus Musa generally have a diploid chromosome number of 2n=20 or 2n=22 (one

species Musa ingens is 2n=14). There are also many triploid (3n) and tetraploid (4n)

cultivars ofMusa used in commercial production. The generaEnsete and Musella bothhave a diploid number of 2n=18.

Banana Morphology

The banana plant (Musa,Musella, and Ensete) looks like a tree but is actually just a large

herbaceous perennial. The banana tree "trunk" is more properly called a pseudostembecause it does not lignify or undergo secondary growth like woody plants do. The

pseudostem is a cylinder of tightly bound leaf petioles that arise directly from an

underground stem, or rhizome. The succulent and juicy pseudostem is not very strong,but can support banana "trees" over 25' tall. The pseudostem color may be green, red, or

purple/black and can contribute to the ornamental quality of the plant. The pseudostem of

Musella is swollen at the base whereas the pseudostems ofMusa and Ensete tend to bethe same width over their entire length. Each pseudostem will produce a single terminal

inflorescence which hangs down beneath the leaf canopy on a long flower stalk inMusa

andEnsete , but faces upward on a short flower stalk in Musella.

Bananas grow from underground storage organs called rhizomes. Musa and Musella,

form offsets freely from the rhizome (suckers) but Ensete almost never forms any. The

main pseudostem of bananas is monocarpic (it dies after flowering) after which the nextoldest sucker grows to replace it. As a result, bananas tend to move around in the garden

a few feet over the course of several years. With most bananas, many pseudostems will

grow at the same time and form a colony covering a small area. Some gardeners maywant to remove all but one or two of the pseudostems in order to preserve the tree-like

appearance of the banana plant, while other gardeners enjoy a large colony. Since Ensete

plants do not sucker, the whole plant dies after it flowers.

The leaves are the main ornamental feature of the banana plant and impart a bold tropical

look to the garden. The smooth, waxy leaves are generally quite large, reaching up to 6"

wide by 2' long on dwarf plants, and up to 2' wide by 9' long on large ones. The leaves

are normally a dark green color, but variegation is quite common. Variegation appears as

white, red or purple/maroon splotches or sectors on the leaf blade. The leaf midrib may

have a contrasting color, which is usually red contrasting with the green leaf. Often, thecolor of the reverse side of the leaf contrasts with the front side and on windy days

viewers are treated to flashes of color. New leaves may open up as one color but

gradually turn another color as they age. The leaves, which emerge tightly curled, arearranged in a spiral pattern around the top of the pseudostem. A single pseudostem may

have as few as four leaves at a time or have several dozen. The amount of leaves that a

banana will retain at any one time is due both to plant genetics as well as growingconditions. In moist, rich soils, a banana will retain more leaves than in a dry, unfertile

soil. The older leaves eventually die and dry up into a brown husk-like form but remain

attached to the stem. Some growers prefer to remove the dead leaves in order to maintain

a tidy appearance.

Banana flowers are very exotic looking. In temperate gardens some ornamental bananas

may not flower because the season is too short. Each species has a set number of months

that the pseudostem must grow in order to flower.Musa velutina, the pink velvet banana,is the only species that can die to the ground in winter and flower and fruit the following

season, requiring only 20 weeks to complete its life cycle. Musella lasiocarpa takesseveral seasons to produce a pseudostem large enough to flower, but when it does, the

inflorescence lasts several months. Reportedly, from research at the Savannah Georgia

Experiment Station, the cultivar Musa 'Vente Cohol' will produce edible fruit as a

dieback perennial, which we are currently testing to confirm. Other bananas must retain apseudostem for more than one growing season in order to flower and produce fruit. In

Zone 8, at temperatures of 15 degrees F,Musa basjoo pseudostems will remain viable

and subsequently flower the following season. All other bananas must have theirpseudostem protected during the winter to fruit the following season.

Technically, the "flowers" are inflorescences (clusters of flowers on a single structure),and a single inflorescence forms on a spike at the top of the plant. Musa and Ensete

flower stalks are long and hang down beneath the leaf canopy, but Musella inflorescences

are borne on short stalks and face upward. Bananas generally will not flower until thereare 9-12 leaves on the pseudostem, so in bananas, size matters. The individual florets are

slim and tubular and are subtended by very large, brightly-colored bracts that may be red,

purple, orange, or yellow. The inflorescence starts off as a large purple tapered bud. The

bud elongates as it opens up, revealing bracts which surround whorls of florets. Bananaplants are monoecious meaning separate male and female flowers are produced on the

same inflorescence. The female florets are grouped together in 5 to 15 rows at the basal

end of the inflorescence, followed by a region of hermaphrodite or neuter flowers.Finally, there is a zone of male flowers near the tip of the inflorescence. The flowers open

sequentially from the basal end to the apical end. The male flowers are shed a few days

after they open, leaving the apical tip of the flower stalk bare, except for the growingpoint. The female flowers grow into bunches of bananas.

The banana fruits are technically a type of berry (a soft multi-seeded fruit developed from

a single compound ovary). The young green fruits resemble green fingers and dangle

down in clusters from the top of the plant. All of the bananas on a single stalk are called a

"bunch". Each cluster of young bananas (which form at a node on the stalk) is called a

"hand" and each banana is a "finger". The number of hands on a flower stalk varies bycultivar. As the fruit matures, it changes color from green to the familiar yellow or to less

familiar shades of red or white. The fruit may even be striped with multiple colors. The

size of the fruit varies by cultivar. The ubiquitous 'Cavendish' is large for a banana butother cultivars are even larger. Bananas range from 2" to 12" in length and from " to 2"

in width. The flesh of the ripe fruit ranges from pure white to various shades of yellow.

Wild-type bananas are filled with 1/8" to 5/8" hard black seeds but do not have verymuch flesh, while the food-type bananas have few or no seeds and are very fleshy. In the

wild, ripe bananas will peel themselves to expose the flesh and seeds. Cultivated bananas

are usually harvested when they reach full size but are not yet ripe. They are then shipped

green and ripened by exposure to ethylene gas when they have reached their destination.

Getting an ornamental banana to produce ripe fruit in a temperate garden is difficult since

many cultivars do not naturally produce ripe fruit until after the growing season is over.

A few of the edible varieties take one month for the flower to develop and two-fourmonths after that for the fruit to grow to maturity. Before freezing temperatures arrive,

cut the entire stalk of bananas and move them to a warm place (like a garage). If they arenearly mature, just hang them up, but if they need to grow to a larger size, place them in a

bucket of water until they mature. In temperate areas with a short growing season, the

trick to getting fruit is to start with a plant that has a well-developed pseudostem early in

the spring. The way to do this is to protect the pseudostem during the previous fall so thatit does not freeze. Refer to the section on winter care for details on this process.

Banana Cultivation

The earliest that you should plant a new banana is well after your average last frost date.

Care should be taken not to expose new plants to temperatures below 57F (14C) whichwill greatly slow the growth. Bananas may be safely planted at any time during the

growing season up until approximately 10 weeks prior to the average first frost date.

Most bananas prefer full sun, although a few varieties with variegated leaves will need a

bit of shade to prevent leaf scorch. See the individual descriptions below for details.

Bananas will grow happily in a wide range of garden soils (sand, clay etc.) but willperform best in a deep, well-drained, organically amended soil. Prepare your banana bed

as you would for most other ornamental plants ... dig a wide hole and amend it with

plenty of organic material. Bananas prefer a slightly acid soil with a pH of 5.5 to 6.5. Dueto the amount and size of their foliage, bananas are very heavy feeders. A good organic

blend is recommended, but keep an eye on the potassium levels, which are very important

to keep high for bananas, so keep plenty of greensand handy, especially if you garden insandy soils. In containers, a well-balanced slow-release fertilizer is perfect.

Bananas are native to tropical areas of the world and are adapted to steady amounts of

rain over a long season. Because the leaves are so large, their evapotranspiration rate is


8/16

quite high. Consequently, they generally do not do well in areas with a pronounced dry

season of 3 months or more without irrigation. Pronounced drought will retard growth

and will result in leaves that burn along the edges. For best results, the general rule ofthumb is 1-2" of water per week.

Bananas (even the cold tolerant ones) prefer warm humid temperatures for maximumgrowth. They grow fastest when the daytime highs are 80F to 95F (27C to 35C).

Growth will slow drastically below 57F (14C). The tops of the plants will die back to

the ground at the first sign of frost.

Bananas are unusually sensitive to strong winds, and the large leaves are easily damaged

by wind or by hail. The leaves tend to rip or shred along the minor veins from the edge of

the leaf inward to the midrib. This greatly detracts from the beauty of the plant andexposes the sensitive fruit to sunburn. Eventually, the damaged leaves will be replaced by

new leaves. Although, winds stronger than 30 mph will only damage the leaves, winds

above 40 mph may cause the pseudostem to break and topple the plant. This will not kill

the plant, but it will ruin any chances for flower or fruit that year. If a storm topples yourplant, the best thing to do is to remove the pseudostem below the point of failure. New

leaves will emerge from the cut end in just a few days. Staking the plant may helpprevent stem topple during storms, but bananas should be protected from high winds by

planting them in a site protected by a wind break such as a building or a hedge.

Growing Bananas in Containers

When growing a banana in a container it is best to remember that most bananas get big

quickly, and will require a 15 gallon container or larger. Watering is dependent on thesize of the plant and the size of the container. Young plants in large containers may need

to be watered every 2-4 days, but when potbound, a daily drenching will be necessary.

Banana growers should re-pot their bananas every 3 years and replace the old soil with a

high quality potting mix. During the winter, gardeners can move the container inside as a

house plant. Bananas will grow fairly slowly indoors so care should be taken to provideplenty of light and humidity, and not to over water. Avoid exposing the container to

temperature extremes. Gardeners may also elect to let their plants go dormant by slowly

withholding water as the weather cools. Remove the main stem and place the container in

a cool dark place such as a garage or crawl-space for the winter. Provide only enoughwater to prevent the soil from separating from the sides of the pot. A dormant banana in a

container can withstand temperatures into the mid-30s F (3 C) using this method.

Winter Care

The main purpose for winter care of bananas is to protect the pseudostem, which allowsfor large plants that may flower and fruit, along with increasing survivability of marginal

plants. There are two techniques for protecting the pseudostem of your banana. First, you

can dig and pot the plant in the fall and keep it growing indoors in a warm location. If

space is a problem, consider digging the plant in fall and store it dormant in a cool


9/16

location that can be kept above freezing. If this still sounds like too much hassle, consider

mulching the plant in the ground. We prefer the latter, since it has proven the most

successful for us and requires less indoor space. Our procedure for overwintering bananasin the ground is as follows:

1. Once freezing temperatures have caused the leaves to turn brown and collapse, cut offthe top of the plant, leaving 3-4' of pseudostem remaining. It is okay to leave the brown

leaves on the plant since they will provide additional insulation.

2. Construct a cage around the trunk using rebar and concrete reinforcing wire (this is asturdier material than chicken wire). Drive the rebar into the ground 2' from the

outermost pseudostem to create supports for the wire. Two or three should be sufficient.

Use the concrete reinforcing wire to wrap the stakes, forming a cage. Secure the wire to

the stakes with zip ties or string.3. Fill the cage with shredded leaves. It is important to shred the leaves since whole

leaves can hold water, clump together and cause the plant to rot. We rake the leaves onto

a lawn area and use a mulching mower to bag them for use. Most municipalities which

collect leaves run them though a large shredder, and the result is usually perfect for thispurpose. Do not use pine straw, hay, or grass clippings since they do provide the proper

amount of insulation and aeration. Without this protection, the plant would die to theground and need to begin from the soil line in spring.

4. When new banana leaves start to emerge in spring, remove the cage and spread the

shredded leaf mixture around the base of the plant where it will continue to decompose

and provide rich compost for your banana plant.

If the mulching we outlined isn't feasible for you, then dig the entire plant from the

ground after it has gone dormant, remove the soil from the roots and wrap the plant firstin newspaper and then in plastic bags. This plant can be stored in a room at 45 F (7 C)

and ignored until spring.

Pests and Diseases

Ornamental bananas are generally pest and disease free in temperate gardens, butsometimes grasshoppers, spider mites or boring insects can attack your plant and are best

treated with general purpose insecticides or miticides. Bananas grown in areas with a

pronounced winter are generally not troubled by the fungal diseases that are rampant in

tropical regions. Ornamental bananas may suffer from winter rot if kept too wet duringtheir dormant period.

Banana Propagation

Musa and Musella are easy to propagate from divisions. Collect the suckers that form,

taking care to include some roots, then allow the cut surface to dry for a day before re-potting. Leave one or two suckers in the ground to replace your plant in case it dies for

some reason. Unfortunately, Ensete almost never produces offsets unless the rhizome is

injured.

If you are lucky enough to get ripe fruit, then you can collect the seed, clean off the pulp,

soak them in warm water over night and sow them immediately. Seed will germinate in 2

weeks to 6 months depending on cultivar. Keep the seedling out of full sun until the firsttrue leaf has emerged.

Bananas are also easily propagated using tissue-culture, which is the process of cloningmassive numbers of plants in laboratory conditions. Most commercially produced

ornamental bananas are propagated via tissue-culture (using shoot tips as the source

material).

Banana Species and Cultivars:

Here at Plant Delights Nursery and Juniper Level Botanic Garden we continue to growand trial a wide variety of cold-tolerant (in USDA zone 7 or 8 at least) species and

cultivars of banana. The information below is a result of our trials.

Ensete

Ensete is a genus of very ornamental non-offsetting bananas, most of which are onlyreliably hardy from Zone 8 south. Ensetes grow best in full sun.

Ensete glaucum (Snow Banana or Elephant Hip Banana)

The snow banana hails from up to 8800' elevation in the Himalayas. The 10' tall, thickbluish trunks support the giant bluish green leaves. Although Ensete glaucum does

produce bananas, we are uncertain of their edibility. What we do know is that the blue

cast of the plant makes this a stunning ornamental banana for the garden. (HardinessZone Zone 8b-10)

Ensete maurelii (Abyssinian Banana)We have long been amazed at this superb ornamental banana from the high mountains of

East Africa. Growing to only 10' tall in temperate climates (20' tall in tropical areas),

Ensete maurelii makes a superb ornamental for the summer border. Each leaf can reachgigantic proportions of 10' long. The most ornamental characteristic is that the foliage is

flushed with burgundy-red, especially concentrated as the new growth emerges. The

higher the light levels, the stronger the coloration. We have also seen this used in large

summer containers to great effect. In Zone 7b, Ensete maurelii overwinters well for us ifwe cover the pseudostem with a 2' pile of shredded leaves after the first frost. (Hardiness

Zone 8-10)

Ensete perrieri (Perrier's Banana)

Ensete perrieri is a little known species ofEnsete from Madagascar with a robust,

beautifully bluish-waxy pseudostem that is distinctly swollen at the base. The straight,ascending leaves with yellowish midribs are held on very short stalks and form a

shuttlecock-like crown. The large maroon flower is held on a short spike at the top of the

plant above the foliage. Ensete perrieri will make a magnificent ornamental for tropical as

well as many temperate regions. (Hardiness unknown)

Ensete superbum may reach 12 ft in height with 12' long massive leaves. The shortpseudostem has a swollen base of up to 8 ft in circumference at the base. The leaves are

bright green in color on both sides with a deeply grooved and short petiole. The fruits are

about 3 inches long and more or less triangular with dark brown seeds. The upper parts ofthe plant die out during a dry season which may give this plant more drought tolerance

than other bananas. The native range runs from India into Thailand, where it grows in soil

pockets on the steep sides of limestone cliffs, hence the common name. (Hardiness Zone8b-10)

Musa species

We are not going to attempt to cover the massive number ofMusa species or cultivars,

but will only a focus on a few that we have found to make great garden specimens in a

temperate garden. MostMusaspecies prefer full to part sun, but full sun and very dry

soils aren't a good combination.

Musa basjoo (Japanese Fiber Banana)Recent research has shown thatMusa basjoo, the world's hardiest banana species, is

actually from Sichuan, China and not Japan. This 16' -- 20' tall running species makes a

thick, green stem that sports 6' long, narrow, green leaves arching from the top of the

trunk. The flower emerges from near the top of the stem like a yellow-orange torpedo.After the flowers open, you will be blessed with clusters of small, yellow, 2" long

bananas. Forget eating this one ... just enjoy the tropical look and tease your neighbors.

We recommend a good mulch in colder regions until the clump becomes well-established. There are hardiness reports thatMusa basjoo is hardy as far north as Zone 4,

but we have been unable to substantiate this with reliable temperature data. If a plant in

Zone 4 is heavily mulched and the temperature only drops to -10F instead of -30 (whichis a true Zone 4), then it probably will survive, but we think these exaggerations are a

great disservice to gardeners. We welcome actual temperature data from Musa basjoo's

survival without protection. (Hardiness Zone 7-10, probably colder)

Musa ornata Purple Flower Form (Bronze Banana)

This dwarf, fast-multiplying Indian species is prized as a container plant because of its

compact, 5-8' tall size, and like Musa velutina, the clump is adorned in late summer andearly fall with upright flower spikes of lilac-purple flower buds that peel open in layers,

revealing the golden yellow flowers. Forget eating this seed-filled banana unless your

spouse kicks you out of the house without dinner. We are just now trialing thisoutdoors ... reports indicate that it is reliable in Zone 8 and possibly further north.

(Hardiness Zone 8-10, guessing)

Musa sikkimensis(Darjeeling Banana, Indian Banana, Sikkim Banana), (syn: Musa

hookeri)

Musa sikkimensishails from high montane forests of the northeast Himalayas.

Reportedly, the trunks can reach 14' in height (ours tops out at 10' tall) with a diameter of

18" or, in other words, about the size of an NFL offensive lineman. The leaf backs

emerge a dazzling cinnamon-red. To say these bananas are edible is about like saying that

Himalayan bathrooms are comfortable ... both have an aroma, but that's about it.(Hardiness Zone 7b - 10)

Musa sikkimensis 'Red Flash' (Red Flash Sikkim Banana)This seed strain ofMusa sikkimensis has a maroon mid-rib, maroon sectors on the top of

the leaf and a totally maroon reverse side. The leaves are contrasted by the yellow flower.

We have not found this to be a reliable leaf pattern from seed, so if you purchase a plantsight unseen, be sure the vendor is reputable. (Hardiness Zone 7b-10)

Musa textilis (Abac Banana)

Musa textilis (often mispelled Musa textilus) is commercially grown in the Philippinesfor its tough fibers, called manilla hemp, that are used in ropes. It grows to 20' tall in

tropics, but our plants have topped out between 8 and 10' tall. Musa textilis has typical

long narrow green leaves with a striking purple/mauve flower and the pseudostem has a

nice glaucous cast. We have grown Musa textilis since 2007, and in that time, it hassurvived 8 degrees F with no mulch. (Hardiness Zone 7b-10)

Musa thomsonii (Thompson's Edible Banana)

This Himalayan species grows to 15' but our plants have topped out with 12' glaucous

grey stems. The new leaves often have a red flush on the reverse side. We have had our

plants in the ground since 2007 and in that time they have survived 9 degrees F withoutmulch. (Hardiness Zone 7b-10)

Musa velutina(Pink Velvet Banana)There's something mystical about a pink velvet banana that makes you want to start

belting out Elvis tunes ... hmmm. Musa velutina was our first introduction to hardy

bananas and is still a favorite in our summer garden. Rarely exceeding 6' tall,Musavelutina produces copious flower stalks near the top of the trunk, starting in late summer.

Each stalk is soon home to attractive clusters of small, pink velvet bananas, which peel

themselves when ripe. Don't plan on a snack from these seed-filled bananas unless youare exceedingly hungry or exceedingly drunk. Once established, they seem to be quite

winter-hardy. Not all strains ofMusa velutina are equally winter hardy, so be sure you

purchase from a vendor who knows if their strain is the most winter hardy. (Hardiness

Zone 7b-10):

Musa yunnanensis (Yunnan Banana)

Musa yunnanensis hails from 8,000' elevation in Yunnan, China and has proven to be anexcellent choice for temperate gardens. For us, this giant reaches 16'-20' during the

growing season despite being killed to the ground in winter. According to the banana

experts, the majority of the plants sold in the US as Musa itinerans are actually thisspecies. Our plants have been in the ground since 2006 and have overwintered at 8

degrees F with no mulch. (Hardiness Zone 7b-10)

Musa Cultivars

Musa 'Ae Ae' (Ae Ae Royal Banana)At one time, ownership of this banana was restricted to Hawaiian royalty, but today

availability has increased slightly. Despite its widespread release, Musa 'Ae Ae' is still

one of the most highly sought-after bananas for ornamental purposes. Musa 'Ae-Ae' willalways remain rare, because this variegation pattern cannot be reliably tissue cultured.

While Musa 'Ae-Ae' is not the most hardy banana, we have been able to successfully

overwinter it using the caged leaf procedure previously described. Of course, winterstorage indoors is always a good option. The 15' tall plants are composed of highly

variegated green-and-white sectored leaves. When the plants mature, you'll get a crop of

edible variegated bananas as well ... how fun! (Hardiness Zone 9-10)

Musa 'Bordelon' (Bordelon Banana) This ornamental banana was first discovered in the

Zone 8b Louisiana town of Bordelonville (near Alexandria). The 10-15' tall stalks are

adorned with red-striped leaves that also feature an attractive red leaf back which is

especially visible when the new leaves unfurl. Based on trials around the country, Musa'Bordelon' appears to be the hardiest of the red-striped varieties. If the growing point is

protected in winter, Musa 'Bordelon' will flower and fruit, although don't plan to makesweet ice cream from these seeded fruits. (Hardiness Zone 8-10, guessing)

Musa 'Darjeeling Giant' (aka: Musa 'Daj giant' Banana)

We purchased these seeds from India as a naturally occurring giant hardy hybrid bananafrom India's Darjeeling Hills region, whose mama was the winter hardy Musa

sikkimensis, but whose baby-daddy was unknown. We're trying these out for the first

time, so we can't confirm the winter hardiness yet. About all we can tell you is that thenew growth has a stunning red-purple back, the flowers are dark purple on the outside,

and the plants reportedly reach 20' in height. Our plants, installed in 2007 are 12' tall and

have survived 7 degrees F without mulch. (Hardiness Zone 7b-10)

Musa 'Helen's Hybrid' (Helen's Hybrid Banana)

This new banana was discovered around 5,000' elevation in the plant rich easternHimalayan region of Darjeeling, India. Musa 'Helen's Hybrid' is thought to be a cross of

Musa sikkimensisand the edible Musa 'Chini-Champa'. The green leaves are

occasionally marked with an upper red midrib, but you can consistently count on bright

red leaf backs on the new foliage. The fruit is sweet, but seedy ... sort of like the "treats"in a cheap Bangkok hotel. So far our plants have reached 8' tall (on the way to a reported

12' tall) and have survived 9F (-13C) in our trials. (Hardiness Zone 8-10).

Musa 'Ice Cream' (Blue Java Banana)

This cultivar is reportedly the best tasting banana available to temperate zone gardeners.

The leaves are silver-green in color as is the fruit. The bananas taste like vanilla custardor ice cream. Sounds delicious! (Sun to Part Sun, Zone 8-10, Ht. 180")

Musa 'Little Prince' PP 15,255 (Little Prince Banana)

This Randy Salter introduction occurred as a mutation on the popular Musa 'Novak'.

Musa 'Little Prince' makes a stocky, 18' tall bold-texture dwarf with green leaves that are

heavily flecked with red (in sun). In colder climates, it can be used as a container plant or

bedding plant for the front of the bed ... yes, bananas and petunias as a bedding scheme.(Hardiness Zone 8b-10)

Musa 'Namwah Dwarf' (Namwah Banana)This edible variety from Thailand has proven to be amazingly winter hardy, sailing

though 8 degrees F without the benefit of mulch. Our two year old plants top out at 8' tall.

To get fruit, Musa 'Namwah' will need to be caged during the winter months. (HardinessZone 7b-10)

Musa 'Orinoco'(Orinoco Banana)

This amazing banana is one of the most cold hardy of the edible fruiting bananas,commonly grown for fruit in the US Gulf Coast region. Musa 'Orinoco'amazes visitors

with its nice fruit clusters in our Zone 7 garden. For us, a height of 10' is common,

although Musa 'Orinoco'can reach 21' in more hospitable climates.Musa 'Orinoco'

requires the pseudostem to remain growing for at least 9 months to produce fruit, so werecommend caging the plants in winter to preserve next year's fruiting stalks. (Hardiness

Zone 8-10, colder with protection)

Musa 'Siam Ruby' (Siam Ruby Banana)

I first saw this raving beauty when visiting Thailand in 2005. At great expense, (I'm still

driving my old vehicle), I procured one to bring home, and over dinner in Thailand, wecame up with the name Musa 'Siam Ruby'. Our research indicated it originated in Papua

New Guinea, where bananas have been cultivated for 10,000 years, as a sport on Musa

'Tapo'. We have never seen it taller than 8', so that's our guess for height. The leaves are astunning, dark ruby red with tiny green flecks ... the more sun, the more intense the color.

This is one banana that loves intense heat and humidity. (Hardiness Zone 9-10, guessing)

Musa 'Truly Tiny'(Truly Tiny Banana)

I fell in love with this 2' tall dwarf while on a trip to Florida ... that is legal in Florida ...

isn't it? Shhhh ... I hear my wife coming down the hall. Musa 'Truly Tiny' makes aperfectly formed but shrunken plant with leaves that are nicely blotched in red. Musa

'Truly Tiny' is great for containers and highly recommended if you are on the South

Beach Diet, since if your plant ever produces a banana, it'll be a "truly tiny" one.

(Hardiness Zone 9-10 at least)

Musella Species

Musella lasiocarpa(Golden Lotus Banana, Chinese Dwarf Banana) This magnificent

ornamental banana is more of a shrub than the typical taller banana. The stiff, thick,

leathery, grey-green, banana-like foliage is borne atop a stalk that can eventually reach 6'in height. Instead of being prized for its fruit, this plant is grown more for its flowers.

Each specimen is home to large, bizarrely beautiful, yellow flowers that look like giant

golden artichokes. Our plants have sailed through over a decade of winters ... and without

any mulch. (Hardiness Zone 7-10)

Summary

Cold tolerant bananas "foster" a tropical look in the temperate garden with their bold

leaves, exotic flowers and colorful fruit. Inspire banana-envy in your neighbors by

growing this wonderful tropical plant in your garden. If you grow bananas in a temperategarden, you'll need some patience since they don't really get started growing until the heat

of late spring arrives. Once you go banana, you'll never go back.
