About This Species
Mountain bluet is a popular garden perennial, however, it easily escapes gardens and invades natural areas. This plant can self-seed, which makes it difficult to control. It also spreads through roots. Mountain bluet is found in meadows, pastures, roadsides and disturbed open areas.
How to Identify
Mountain bluet ranges from 30-80 cm in height. Flowers are large, bright blue with a ray-like appearance and black fringe at the base and look a lot like knapweed flowers. Fine hairs cover the stem. Leaves are 10-30 cm long, lance shaped, with a wooly underside.
