A large-flowered selection of one of our native North American ornamental onions. This forms a low tuft of grassy leaves, bearing taller stems with nodding heads of rosy-lilac bells in early summer. Adapts to sun or part shade, and a wide range of soil types. Nice in the rock garden or perennial border. Dried seedheads remain attractive well into the winter. Received a Royal Horticultural Society Award of Garden Merit (1993). Easily divided in spring or fall, if desired. Plants may also self sow. Flowers are attractive to butterflies and also good as a cutflower. Sometimes listed as A. cernuum major.
