Cup Plant is a bold prairie native that creates tall towering stems topped with bright yellow flowers from the midsummer into early fall. Its impressive height and long bloom period make it a standout in meadows and pollinator gardens where it provides lasting color and structure.

The leaf bases form small cups that collect healthy portions of rainwater, giving birds and beneficial insects a dependable source of drinking water during the growing season. By late summer, its cheerful blooms become an extremely lively gathering place for butterflies, native bees, and goldfinches.

*Cup Plant does have a tendency to spread quite a bit.
