Apocynaceae (Dogbane Family)
Eastern bluestar is a 1-3 ft., erect-stemmed perennial
forming large, multi-stemmed clumps. The smooth stems are crowded with narrow, oval
leaves which turn golden-yellow in the fall. Blue, tubular flowers, the rim flaring to a star-shape, appear in loosely conjested clusters at the tips of the stems.
The species name commemorates the 16th-century German herbalist Jakobus Theodorus Tabernaemontanus.
