Allium ostrowskianum

Ornamental Onion

Related to Onions, Garlic and Leeks, Ornamental Onions are grown for their dense clusters of flowers, which look like lollipops. Height varies from 6 inches to 5 feet. Use for rock gardens, naturalizing and flower borders. Smaller-growing varieties are good in containers. Excellent cut flowers. Leaves smell like onions. Use fully-ripened stalks in dried arrangements. Many are sun-loving and hardy to Zone 4 if mulched in winter. They are easy to grow. Plant bulbs in fall no more than 2 to 4 inches deep, depending on bulb size. Bulbs prefer sandy soil and will rot without excellent drainage. For most species, when foliage yellows after flowering, gradually withhold water. Susceptible to all pests of edible Onions, but usually trouble free.
