Description

Summer Lilac Buddleja is a deciduous woody perennial shrub in the figwort family. It is native to China and has great foliage interest with gorgeous silver leaves that contrast well with other darker green plants in the landscape. The shoots are covered in soft silvery downy hairs.  It requires protection in cold winters or it may die back to the ground.  It will usually grow back the following spring.  Prune it back hard every spring to encourage new bushy growth.   Propagate it by division in the fall or softwood cuttings in the spring.  This plant is drought and pollution tolerant and grows more slowly than B. davidii.

Insects, Diseases, and Other Plant Problems: It can be weedy.
