The flowers are clustered in groups of two or three, and are borne out of the leaf axils. [13] The corolla bears 4 petals. [14] The globular fruits are burrs which grow one to three seeds clustered together; they are covered with hooked hairs which cling to animal fur and human clothing, aiding in seed dispersal. [13]

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. [4]
It has small white or pink flowers year-round at the base of leaf stalks; flowers have 4–10 mm long petals. [5] [7] The 2 mm seeds are reddish-brown and kidney-shaped. [7] Newly sprouted plants have hairless, heart-shaped cotyledons with long stalks. These cotyledons are 3–12 mm long and 3–8 mm wide. Stalks usually do have hairs.
