Botanical Name

AMSONIA tabernaemontana var. salicifolia

Plant Common Name

Willowleaf Eastern Bluestar

General Description

Willow-leaved blue star is a vigorous herbaceous perennial prized for its size, distinctive fine texture, starry flowers, and its golden fall color. In spring, thin unbranched stems rise from the center of the roots. The inner stems grow upright while the outer stems lean slightly, giving the plant a spreading silhouette with a rounded crown. The willow-like leaves of this variety are much narrower than those of the species and grow almost at right angles to the stems, producing a resemblance to a bottle brush. Growing close together, the stems and leaves give the plant a fine, tidy texture.

This tough, vigorous native of the southeastern U.S. is easily grown in average, well-drained soil in full sun to part shade. It grows and flowers best in moist, loamy soils, but tolerates some drought.

Use this perennial in a mixed border, as a specimen plant, in an open woodland area, or plant three or four together to create a mass resembling a shrub in summer and fall.
