Traditional Herbaceous Border
• Traditionally the most common way of growing hardy herbaceous plants were grown together in long rectangular plots dating back to the Victorians era.
• These borders tended to be backed by a hedge or wall and being framed by lawn or bordered by a path.
• Plants were arranged according to height with tallest herbaceous plants at the back of the border with the shortest at the front.
• Herbaceous plants are grown in drifts and in odd-numbered groups to achieve the greatest impact.
• Personal taste and style of the garden or house can dominate the colour schemes and style.

Prairie Planting
• This is a recent fashion that does away with lawns and beds. Instead, paths of bark or gravel wind through a dense carpet of low-maintenance perennials, through which pop occasional clumps of taller ornamental grasses and perennials.
