Plant Origin Matters
Origin of native wildflowers could affect performance and survival.

All of these wildflowers ….
• Adapted to our climate• Can be thought of as Florida
“ecotypes”
![Page 13: Overview of Native Wildflower Seed Production in Florida Jeffrey G. Norcini University of Florida/IFAS North Florida Research & Education Center, Quincy](https://reader038.vdocument.in/reader038/viewer/2022110207/56649d885503460f94a6e078/html5/thumbnails/13.jpg)
• Population of a species that’s adapted to a particular set of environmental conditions
• Occurs via natural selection
What is an ecotype?

The bottom line…
The origin of the seed or plant can make a difference in performance.

Advantages of Florida ecotype
• Longer living• Longer flowering• Longer period of seed production
facilitates long-term sustainabilityfacilitates expansion of population
Implications? Rudbeckia hirta
