Amsonia tabernaemontana, commonly called bluestar, is a Missouri native herbaceous perennial which occurs most frequently in rich, open woods and thickets in the southwestern part of the State. An erect, clump-forming plant which features terminal, pyramidal clusters of 3/4", soft light blue, star-like flowers in late spring atop erect, leafy stems growing 2-3' tall. Narrow, willow-shaped, dull green foliage may turn an attractive yellow in fall.
Specific epithet honours Jakob Theodor von Bergzabern (d. 1590) who Latinized his name as Tabernaemontanus.
‘Short Stack’ is a dwarf variety of bluestar that typically grows to only 10” tall and to 18” wide. This cultivar was introduced into commerce by Plant Delights Nursery in North Carolina under the name Amsonia montana ‘Short Stack’. Some confusion exists as to whether Amsonia montana (typically small-leaved, low-growing forms of A. tabernaemontana) is a recognized separate species. It is listed herein as a cultivar of Amsonia tabernaemontana.
