All I have is my imagination and resourcefulness to make this one happen. I used young plants that are much less costly than mature perennials. When buying young plants, softly tap them from their pots to make sure they have developed a sturdy root system. Look for at least three or four good, big, well attached main roots. If you can see a well-developed root system beginning, place it back in the container and purchase the plant.
Perennials grow to twice their size in as little as one year.
They can grow even bigger by the third year. When planting a perennial garden using young plants, make sure that you leave plenty of space between plants. Do not plant anything else within a 3-foot radius of the first plant. Overcrowding perennial plants leads to root competition. This will lead to poor plant health.
