Description: Beautiful yellow flowers bloom at the end of June to early July.  This is a very nice plant to be used in masses in front of taller plants. It occurs in northeastern Illinois along Lake Michigan. In Illinois, this shrub is rare and state-listed as 'endangered.' Habitats include interdunal swales, borders of small sandy ponds, moist to wet sandy meadows, and moist sand flats (pannes). Bees love this plant for its pollen (no nectar is available).
