Light pink, ping pong ball-sized blooms appear above the twisting green leaves in July on this rhizome-producing (not bulb) ornamental onion. In Chicago-area gardens, the ornamental onions producing rhizomes are better adapted to our heavy soils that often get excessively wet during periodic rainy periods. Plant in full sun in average soils and avoid crowding, shading, or disturbing the plant for several years. It will slowly increase in size to form a beautiful display. Honeybees in particular are fond of onion flowers, but close observation will discover a wide range of pollinators visiting the flowers.
