Bluet is a common and popular perennial of Czech gardens and lower mountains. It produces 30-60 cm tall stems with bizarrely shaped, antler-like, purple-blue flowers from early June until midsummer. Deciduous leaves are light green, slightly hairy.

In the wild it is considered endangered species. Grow it in a sunny border or in part shade along with other perennials that will help it remain erect. It needs free-draining soil that is medium fertile and preferably evenly moist rather than dry on hot summer days. Hardy to about -40°C (USDA zone 2)
