It's a wide, white cloud at the rear of the garden view in August, most attractive and cheerful. I would not want to be without it.

I prefer Kalimeris pinnatifida for a similar garden role. Tough, adaptable, drought tolerant, tolerates partial shade, needs no maintenance, self-supporting, has a longer season of bloom, foliage looks good at all times, even the dried stalks look good into winter.

Tall 4' - Plant 24 "apart. Masses of starlike white flowers atop sturdy plants beginning in the late summer and continuing until and after frost.

Shorter than the species; seed collecting will not yield plants true to the parent. Divide the rhizomatous roots in spring to increase stock.
