This species is notable in stature, forming a giant mound and producing a profusion of airy white flowers on tall stems in late spring to midsummer and then dying down in midsummer to late summer. Colewort can reach 8 feet high and about half as wide. Grow in a large border or open woodland.
Noteworthy Characteristics:  Large leaves and abundant flowers.
Care:  Prefers fertile, well-drained soil in full sun, but will tolerate poorer soils in partial shade. It is susceptible to rot in moist soils, and may be short-lived. It tends to survive winters beyond Zone 6.
Propagation:  Sow seed in a cold frame in spring or fall.
Problems:  Clubroot, black rot, slugs, snails.
