About plant names...

Showy aster is native to North America, but it is now threatened over much of its range.

Identification: Plants are 4-35" (10-90 cm) tall, with stiff stems and sticky hairs, often branching toward the top. Leaves are alternate, unlobed, mostly toothless, rough or hairless, and ⅜-6" (1-16 cm) × ⅛-1½" (3-40 mm). In botany-speak, their shapes are lanceolate or elliptic to ovate- or obovate-elliptic or spatulate. This translates roughly to rounded or spoon-shaped. Leaves may be attached directly to the stem (sessile), or on short winged petioles. Flowerheads are a flat-topped corymb. Individual flowers are up to 1½" (3.8 cm) across, with 15-35 blue to purple rays and 25-55 tiny flowers in the central disc.
