Eastern Bluestar is a perennial, erect, clump forming plant grows from 1 to 2-1/2 feet high with leafy light green smooth stems that are slightly angled.

The leaves are alternate, bright green, up to 6 inches long and 2-1/2 inches wide with smooth margins, a single main mid-rib vein, and a slender stalk - like willow leaves. The upper surface is smooth, but the underside may have fine hair, especially when young.

The inflorescence is a loose cyme of individually stalked flowers atop the stem.

The individual flower has a tube shaped corolla with five strap-like spreading lobes. Each lobe is narrow, tapering to a pointed tip, and the effect is star-like when the flower opens and the lobes spread outward horizontally. At the base of each lobe is a paler patch of color - either white or yellow, above which are numerous stamens. The corolla can be whitish early on if there is too much shade, otherwise it is a very nice pale blue. The exterior corolla of the flower is a deeper shade of blue than the interior - quite striking. The throat of the corolla has a band of fine hair. The green calyx has 5 triangular teeth. Each flower spans about 3/4 to 1 inch.

Seed: Mature flowers produce a cylindrical follicle that splits along the side to release its seeds. Amsonia seeds need at least 30 days of cold stratification for germination.

 

Habitat: Eastern Bluestar will grow in average well drained soils in full sun to partial shade. The more shade, the lighter the color of the corollas, plus, the plants will become floppy. There are a number of cultivars available in the nursery trade.

Names: The genus Amsonia, is an honorary used for blue-flowered herbaceous perennials and named for 18th century Virginia physician Dr. Charles Amson. The species, tabernaemontana, is another honorary, named for Jakob Theodor von Bergzabern (d. 1590), who Latinized his name to Tabernaemontana. He was the personal physician of the Count of the Palatine, Heidelberg, Germany and published a herbal titled Neuw Kreuterbuch in 1588-91. The author name for the plant classification, 'Walter', is Thomas Walter (c1740 - 1789) a botanist known for his book Flora Caroliniana (1788) an early catalog of the flowering plants of South Carolina where this particular species grows. The alternate common name of Willow Amsonia refers to the plant's willow-like leaves.
