Habitat and Conservation
Occurs in dry upland woods, wooded or open slopes, and ledges of bluffs; in dry, rocky soils derived from chert, granite, or limestone; mainly on acidic but also on lime soils.
This is a great native choice for a sunny Missouri rock garden, but do not dig plants from the wild. Instead, visit a local native wildflower nursery that propagates the plants ethically. Some special cultivars have been developed with unique colors.
A variety of butterflies, moths, and skippers drink nectar from the flowers. A variety of insects and mammals eat the foliage. Plants that grow in thin, rocky soils play an important role in preventing erosion, which is one reason you should not dig them up, or even trample them.
