Flowering - April - May.

Habitat - Dry to moist low woods.

Other info. - To me this is one of the best looking plants of the genus. Typically this genus is weedy and troublesome but this species is native and adds a surprisingly brilliant splash of white for such a small plant. I don't know if it is cultivated, but it would make a neat border.
