Doellingeria umbellata (Mill.) Nees var. umbellata Flat-topped white aster, umbellate aster, parasol whitetop, tall flat-topped white aster
Flat-topped white asters are natives of North America. Identification: These asters are named for the tendency of their flowerheads to form a flat-topped mass, but they may also be rounded. Plants are 20-79" (50-200 cm) high. Stems are green, sometimes purple or yellowish-brown. Leaves are 2-4" (6-11 cm) long by ½-⅞" (1.3-2.5 cm) wide. 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. Flowerheads are panicles 3-12" (7.6-30 cm) around. Individual flowers are about ½" (1.3 cm) across, with 5-12 white rays and 12-25 tiny florets in the central disc. The disc is yellow, aging to tan-colored. See our aster comparison table here. Or check Arieh Tel’s well-researched and informative aster comparison site. Online References:
