Detailed Information

Flower: Flower shape: 4-petals Cluster type: raceme

[photo of flowers] Flowers are sparsely arranged in a spike-like raceme, 4 to 16 inches long. Individual flowers are white to greenish white, sometimes pinkish, 1/8 inch long with 4 pointed-tip petals. 4 stamens protrude slightly from the center. One terminal spike is normal, but a plant may branch and have multiple spikes.

Leaves and stem: Leaf attachment: alternate Leaf type: simple

[photo of leaves] Leaves are broad, up to 6 inches long and 3 inches wide, rounded at the base and sharply pointed at the tip, on short stems. Leaves are usually hairy on both sides, but may be hairless on the underside. The main stem is hairless, except for nodes surrounding the main stem at the leaf axils.

Fruit: Fruit type: seed without plume

[photo of fruit] Fruit is an oval, dry seed with the remains of the style hanging off the tip. When ripe, it jumps off the stem at the slightest touch, hence the common name.

Notes:

Jumpseed often goes by Polygonum virginianum but the accepted name in Minnesota is Persicaria virginiana.
