Allium stellatumAlso known as:
Allium stellatum is a native onion with foot-long, flat, solid leaves. A single flowering stalk emerges in summer, as the leaves begin to wither, and is topped by a 4" umbel of pinkish or purplish flowers. These can persist for three weeks or more.
Allium stellatum is easy to grow in average garden conditions. It is however adapted do dry, poor, sandy or rocky soil. This makes the plant an excellent choice for a rock garden. It will tolerate some shade, but full sun is best. It has very deep roots for such a small plant, and is thus quite drought resistant once established. Best grown in groups. Take advantage of its small size, and the fact that the leaves die back in summer, to use them as a transitional flower, between spring and fall bloomers. This can easily be controlled by deadheading spent flowers. Very cold hardy. Zones 3-8.
Can be propagated by seed, however plants will take several years to mature enough to produce flowers. Separate and replant bulbs in early fall, when the plant has gone dormant.
Like with other onions, rabbits and deer will shy away. The bulbs and leaves are edible, both raw and cooked, but contain low levels of toxins that can cause discomfort if ingested in large quantities.
