Perennial plants are one of the largest groups of plants.
They offer color, shape, fragrance and seasonal textures. The variety is such that there are plants to suit all sizes and styles of garden.
Traditionally, perennials are grown in borders, using a wall or hedge as a backdrop to bring out all their splendor during summer.
But since most gardens are not large enough for long borders dedicated exclusively to perennials, they are usually planted in mixed borders and beds, along with shrubs, annuals, biennials, and bulbs that extend the season of interest.
