Tim has 80+ different varieties of perennials and grasses for sale. Perennials CAN be planted all throughout the season, not just early spring or fall. As long as you water, care and fertilize them, they will do their job for you and bloom for many years. Decide what type of area you have, sun or shade, and when you want them to bloom: early spring, summer or fall. Many perennials will bloom almost the entire season under the right conditions.
