Submitter has sample
These are individual stalks topped by short columns of clustered lavender or white florets, each stalk surrounded by a circle of blade-shaped leaves. Each plant grows from a large white bulb that multiplies copiously 4-8" beneath the soil. They are very pretty so I have not tried to eliminate them in past years. However this year they have completely invaded all my flower beds. Don't know how to get rid of them except by digging each plant up separately.
