- Description
-
Pasture Thistle is a native biennial or monocarpic perennial in the aster family found from Maine south to SC. It is found in the Piedmont of NC in pastures, lawns, meadows, woodlands and sandy floodplains. It has a long taproot and can be hard to get rid of if so desired. The stems and leaves have prickles so wear gloves. The disc flowers bloom in purple, pink, or white and attract butterflies, bees and birds. The plant lives 1-2 years, then blooms, sets seed and dies.
This plant could be used in a naturalized area for pollinators and birds to enjoy. The flowers are actually showy and fragrant. It is drought tolerant and prefers full sun and dry, well-drained soils.
