It blooms close to the ground from June and continues throughout the summer atop 6-foot-tall stems. The large, white, astilbe-like blossoms fade to pink and then reddish-brown as the season comes to a close. Noteworthy Characteristics: Persicaria are rhizomatous or stoloniferous plants that are spreading and sometimes invasive. They have fleshy stems and conspicuously veined leaves, some of which exhibit autumn color. Many are suitable in a mixed container or border, others naturalized in a woodland or meadow. All plant parts may cause skin irritation on contact and stomach upset if ingested. Care: It prefers moist soil but can tolerate some shade and dry conditions. Propagation: Divide in spring or fall. Sow seed in spring in a cold frame. Problems: Aphids, Japanese beetles, slugs, snails. Overview Height 3 ft. to 6 ft. Spread 6 ft. to 10 ft.
