PurpleOrnamental Onion Growing and Maintenance Tips
Leaves die back as flowers begin; don't cut back foliage as it feeds the bulb for next year's flower. Once the flower is spent, remove the flower stalk and leave the foliage until it completely dies back, it can then be removed by gently pulling on the leaves. Do not over water and let the soil dry out between waterings.
