- Description
-
Blue Star is a clump-forming herbaceous perennial in the dogbane family that is native to the southeast and west to Texas. It is generally found in sandy soils, where it does best. It typically grows to 1-2’ tall but can be pruned back to 8"-10" above the ground after it flowers to help give it a more compact rounded shape. In addition to its lovely blue spring flowers, the foliage adds an airiness to the garden and then has lovely yellow fall color. For the longest-lasting flowers, give the plant some afternoon shade. Fall color is best when grown in full sun. The stems may flop with too much shade.
Blue Star prefers sandy very well-drained soils in full sun but will tolerate light shade. To much shade will cause flopping of the flower stem and poor fall color.
Insects, Diseases, and Other Plant Problems: No serious insect or disease problems.
