Butterfly bushes are also known as Buddleia. They grow 10 to 12 feet high and require pruning to keep their shape. Butterfly bushes die back to the ground each year in colder areas but are evergreens in southern areas. They require full sun exposure and grow well in normal, clay or sandy soil types; however, well-drained soil is best for these bushes.

There are over 100 species of butterfly bushes. These bushes can produce pink, white, dark purple, orange or gold flowers. Black Night is a variety that can grow up to 15 feet tall and produces shorter flowers than most of the other varieties. Royal Red grows up to 6 feet; its branches weep instead of growing upright.

Butterfly bushes should be watered once a week, depending on the weather. They may be pruned at any time, and they can be cut completely to the ground during the dormant period. The dormant period usually begins after the first frost. Applying compost and mulch each year helps the plant retain water and controls weeds.
