From Wikipedia, the free encyclopedia

Persicaria virginiana, also called jumpseed, Virginia knotweed or woodland knotweed is a North American species of smartweeds within the buckwheat family. It is unusual as a shade-tolerant member of a mostly sun-loving genus. Jumpseed is a perennial, named for its seeds which can "jump" several feet when a ripe seedpod is disturbed.

 

Persicaria virginiana blooms in midsummer to late summer/early fall. It has a stalk of small white flowers.

Like other Persicaria, jumpseed has alternate leaves, with fine-hairy stipular sheaths (ocrea) with bristle-fringed edges which often turn brownish. Flowers, widely spaced along slender stalks, are white to greenish-white, rarely pink-tinged, and fruiting flowers have 2 downward-pointing hook-tipped styles. Persicaria virginiana is easily distinguished from most other Persicaria species by its much larger, more oval-shaped leaves, although a few species also have large leaves. It sometimes has a chevron-shaped marking on the leaves; often a single plant will have this marking on some leaves but not others.

Cultivars and naturalized populations from cultivation show much greater variation than wild-type plants, sometimes having variagation or have more involved red patterning, and sometimes having red or pink flowers.
