Prairie Thistle is a wildflower species that typically grows about 0.5 m in height. This plant may also be known by the common name Flodman’s Thistle. The leaves are alternately arranged, dark green coloured, covered in hairs, and have deep, wavy, spread out lobes with sharp spines at the tips. The flowers are pinkish purple, appear on branching stems out of spiny bracts, and bloom between June and August. The flowers are beneficial to pollinator species, like bees and butterflies.
