2025 SGCN Priority Tier: Highest Conservation Concern

Perennial herb, sometimes forming large colonies by the spread of rhizomes. Belonging to the aster family (Asteraceae), it stands out among most Coreopsis species for its distinct love of rich, wet soils and its exceptionally late autumn bloom time

It prefers full sun to partial shade. Unlike its drought-loving relatives, C. integrifolia relishes moisture and thrives in average to wet soils, effortlessly handling several days of inundation.

This species is an excellent choice for rain gardens, native plant gardens, boggy areas, and pond or stream edges. It spreads slowly by underground runners to form modest, well-behaved colonies that serve as an effective groundcover.

It is highly valuable for supporting native bees and butterflies with a late-season nectar meal when other flowers have faded. Birds also utilize the seed heads late in the year.

 It exhibits good deer and rabbit resistance

Host plant for several moth species including the Wavy-Lined Emerald Moth, Dimorphic Gray Moth and the Silvery Checkerspot Butterfly.
