- Description
-
This low maintenance plant is an uncommon herbaceous perennial in the Apocynaceae family. It is native to the Ouachita Mountains in central Arkansas, where it was discovered in the early 1940's by Leslie Hubricht. It is easily grown in average, medium, well-drained soil in full sun to part shade. A slow grower, it may take 1 to 2 years before this plant's true beauty can be seen. It forms erect clumps with feathery green foliage, making it an excellent backdrop for low growing annuals and perennials.
In the spring it produces blue star-like flowers; after flowering, slender, elongated seed pods form.
From a distance, this plant may resemble a lily plant. It is prized for its great fine texture and bright yellow fall color. Use in borders, rock gardens, as a native plant, in open woodlands, and in mass plantings.
Insects, Diseases and Other Plant Problems: No serious insect or disease problems. Plants can flop over with too much shade, so cut back after flowering. Caution should be used when cutting back, as the milky white sap can cause skin irritation.
