Genus:Cirsium

Species:pumilum

Family:Asteraceae

Pasture Thistle is a biennial or monocarpic perennial belonging to the aster family, thriving from Maine down to South Carolina. In North Carolina's Piedmont region, it can be found in various habitats, including pastures, lawns, meadows, woodlands, and sandy floodplains. This plant features a deep taproot, making it challenging to remove if necessary. Its stems and leaves are equipped with prickles, so it's advisable to wear gloves when handling it. The disc flowers, which bloom in shades of purple, pink, or white, are particularly attractive to butterflies, bees, and birds. The plant has a lifespan of one to two years, during which it flowers, produces seeds, and ultimately dies.

In a naturalized setting, this plant can serve as a valuable resource for pollinators and birds. Its flowers are not only visually striking but also emit a pleasant fragrance. Additionally, it is drought-resistant and thrives in full sunlight and dry, well-drained soils.
