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.
