[MAIPC] Incised Fumewort (Corydalis incisa)

[Vanderhorst, James P]

There is one WV record on iNat from Morgantown.
https://www.inaturalist.org/observations/44919052

The record says "Organism is wild" but the location is a residential
neighborhood, so?

For sale in WV at:

a nuisance or a plant that I would consider invasive,  it joyfully self
seeds itself."
