2-3'H Perennials
These medium height perennials usually remain in the 2 to 3 feet high range under most conditions. Use them behind and among lower growing perennials, as specimen plants near the middle of border, in front of medium sized shrubs and other taller perennials, and around tree form plants. Many of these will make nice container specimens for medium sized containers and in combinations in large and very large containers. Growing conditions and how well a plant is established may affect your plant's ultimate size.
