    I've seen this perennial woodland forb for decades in the woods and did not know what it really was, except some kind of Smartweed. This Jumpseed or Virginia Knotweed or Woodland Knotweed or Virginia Smartweed is native to southeast Canada, New Hampshire down into northern Florida to east Texas up through eastern Nebraska through Minnesota back to Canada. It is called Jumpseed because if one disturbs the flower-seed scape with the ripe seed, the seed are propelled several feet up to 9 feet away. The seed can also hitch a ride on the fur of mammals because of little hooks on the seed. The leaves are up to 6 inches by 3.5 inches in size with rounded bases and pointed apexes. The flowering scape is terminal as 1 or 2 together being a spike-like raceme with tiny white flowers that are spaced far apart and bloom from July to October. The root system is both fibrous and rhizomatous, so a colony forms from the underground stems, besides the seed. It is pollinated by bees, bumblebees, and wasps and ants like to get some nectar, though not pollinating the flowers. I don't know of any nurseries selling this species, but there could be a few native plant nurseries that do such. One note is that some botanists have recently given this plant the scientific name of Antenoron virginianum.
