ALLIUM. Widespread, Northern Hemisphere. In addition to such food plants as the onion, garlic and chives, the alliums include many fine ornamental bulbs for border, rock garden and container culture. A few are evergreen; most are deciduous at some time of the year. Most have narrowly strap shaped to cylindrical basal leaves during the growing season, and all display small 6-parted blossoms in umbrella-like clusters (sometimes contracted into spherical heads atop naked flowering stalks). Sun, reasonably well drained soil, moderate watering. The following should be hardy to 10oF. or less.
dichlamydeum. This is a small plant (under 1'), each bulb producing a few narrow, flattened, blue-green leaves and in late spring one or more stems displaying dense clusters of tiny dark pink blossoms. Summer dormant and drought tolerant.
unifolium is one of the showiest and most easily grown of our native bulbs, quickly forming many-stemmed colonies. It has narrow, flattened 6-12" leaves and large clusters of pink blossoms on 1-2' stems, appearing in late spring. Summer dormant and drought tolerant.
