Unlike invasive thistles, Pasture Thistle is native to North America and plays a crucial ecological role without being aggressive.
After flowering, its seeds become a major food source for goldfinches and other seed-eating birds in late summer and fall.
Supports the larvae of several butterfly and moth species, including Painted Lady butterflies.
