Perennials and biennials are the foundation on which any prize-winning flower garden is built. With the variations in flower form, flowering times and duration of bloom, the features of a perennial garden provide a succession of bloom which is always changing as the seasons do. Some simply lose their leaves come winter, some stay evergreen and perennial grasses wave in the breeze and change colour for a four season show.
In new perennial gardens, mixed plantings of annuals and perennials are a great way to provide more bloom for a longer time. There is less planting of annuals year after year as the perennials gradually fill in and take over.
Perennials can be started indoors or directly sown outdoors in spring, late summer or in fall. For best results, follow directions on the package.
