This is one of our larger (taller and larger flowers) Coreopsis species. Useful as a colorful wildflower along the edge of a wetland. Often overlooked as sunflowers are blooming at the same time. But if the site is appropriate, worthwhile.

Rare and listed as endangered. Please obtain this plant only from reputable native plant nurseries or friends -- do not harvest from the wild. Little is known about the culture of this species. Other Silene species do well if divided at the crown during the winter every few years. Groundcover.
