Noteworthy Characteristics
Symphyotrichum anomalum is a Missouri native perennial which occurs in dry or rocky woods and thickets in the Ozark region of the State. It is a stiff plant typically growing 2.5-3.0' (less frequently to 4') tall with an upright habit. Features a profuse bloom of daisy-like asters (to 1/2" diameter) with purple rays and yellow centers from late summer well into fall. Lower lance-shaped leaves (to 3.5" long) have untoothed margins and are heart-shaped at the base. Smaller lance-shaped upper leaves clasp the stem. Flowers are attractive to butterflies. Formerly know as Aster anomalus.
Genus name comes from the Greek symph meaning coming together and trich meaning hair in possible reference to the flower anthers.
Specific epithet means deviating from the normal.
Problems
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.
