This plant has reached a height of 9' in my seasonal stream bed. I'd class this plant as totally care-free. The leaves are coarse and they aren't pretty, but I find it to be a very nice background plant for a nearly-wild area.

Midwest Indian tribes used this plant as a remedy for the 'fits' (Mesquakies), as a snuff to stop nosebleed (Chippewas), and as a beverage tea (Omahas). Early settlers likewise used the leaf in a tea as a spring tonic known as "simpler's joy" (an olden term for 'herbalist').
Vervain likes low wet areas, wet prairies, wet meadows, wet woodlands, stream borders, pond edges, low pastures, and along roadsides.
Flowers form a ring on spikes ('pencil-like') that start blooming at spike's base and seem to advance upward.
Roots are fibrous and short rhizomes
Seed (roasted), leaves (tea, salads), and roots are edible.
