Local at the base of steep east- (to quite locally south-) facing bluffs. Occasional here in a small (~1/4-acre) groundwater seepage zone dominated by Nasturtium officinale, especially along the more degraded margins of the seep. Gently-sloping, sunny setting on the river bank, a few feet above river level. Wet sandy substrate, often with a shallow organic cap. Pale blue flowers.
