Noteworthy Characteristics:
Aster patens is a Missouri native aster which occurs in rocky or sandy open woods, thickets and glade margins in the Ozark region of the State (Steyermark). It is an upright plant that typically grows to 2.5 tall on slender, hairy, brittle stems. Features daisy-like asters (to 1" diameter) with blue to violet rays and yellow centers from late summer well into fall. Flowers appear singly at the ends of slender stems. Untoothed, stem-clasping, ovate-oblong leaves (to 2" long) are rough-textured and hairy. Commonly called spreading aster or late purple aster. Flowers are attractive to butterflies.
No known serious insect or disease problems. Asters generally have some susceptibility to powdery mildew. Aster wilt can also be an occasional problem, particularly if plants are grown in poorly-drained clay soils.
Uses:
Native plant gardens, open woodland gardens/areas, cottage gardens or butterfly gardens. Although it grows up to 30 inches tall, this aster is native to rocky soils and will do well in similar soils at the periphery of a rock garden
