CHRYSANTHEMUM weyrichii 'White Bomb'
Plant Common Name
Weyrich's Chrysanthemum, White Bomb Chrysanthemum
White Bomb chrysanthemum is a hardy mat-forming perennial that is densely covered in white daisy-like flowers in late summer or autumn. The white petals circle a central disc of yellow. Native to the Kamchatka Peninsula of Russia and the tiny islands north of Japan, this low but vigorous spreading plant has fleshy, aromatic leaves that are jaggledly five-lobed rising from a woody rhizome. It is a late-season source of nectar for butterflies.
Plant this chrysanthemum in a fast-draining soil, either sand or loam-based, in full sun. It is relatively short-lived in heavier soils. It works nicely as a groundcover on rocky hillsides or screes or in the sunny mixed border. Oils in the foliage can be slightly irritating to those with skin allergies.
