About plant names...

Flat-topped white asters are natives of North America.

Plants: These asters are named for the tendency of their flowerheads to form a flat-topped mass, but they may also be rounded. Plants are 1½-6½′ (50-200 cm) high. Stems are green, sometimes purple or yellowish-brown.

Leaves: 2-4″ long ⨉ ½-⅞″ wide (6-11 ⨉ 1.3-2.5 cm). They are smooth when rubbed in one direction, rough in the other, elliptic or lanceolate-elliptic. They have prominent veins, a distinctive characteristic, and pale or whitish green undersides.

Flowers: Flowerheads are panicles 3-12″ (7.6-30 cm) around. Individual flowers are about ½″ (1.3 cm) across, with 5-16 white rays and 12-50 tiny florets in the central disc. The disc is yellow, aging to tan-colored.

Fruits: Dry seeds with miniature parachutes.
