This short, squat perennial bulb looks great from the moment it emerges in late winter until it dies down in summer. It is one of the few ornamental onions with beautiful foliage. Two fabulous soft gray blue-green broad leaves give an early show. Then in early spring a short flower stalk emerges and opens to a perfect globe of white stars. Once the flowers finish the faded seed heads look like small sunbursts on dried stems. This drought tolerant bulb is excellent for hot dry sites and loves to bake during the summer months.

- Culture Notes
- Ornamental onions grow best in full sun and sandy soil. They will tolerate a heavier soil as long as it is very well-drained or even clay soils if the location is sloped and water does not puddle in the winter. Leaves will grow through the late winter and spring, only dying back as the bulb begins to flower. Yellowing leaves can be trimmed to the ground or hidden amongst other plants. Bulbs can be planted in the fall.
