Allium Unifolium (Oneleaf Onion) is a compact perennial with delicate clusters of up to 30 fairly large, star-shaped, satiny, rose-pink flowers. The blossoms are borne atop the foliage of short gray-green basal leaves. Blooming in late spring to early summer, this charming Allium spreads freely in the garden without being a pest.

• Recipient of the prestigious Award of Garden Merit by the Royal Horticultural Society
• Grows up to 12-24 in. high (30-60 cm). This Allium naturalizes easily and will slowly spread to form lovely colonies.
• Easily grown in fertile, dry to medium moisture, well-drained soils in full sun.
• Stunning in beds and borders, or rock gardens. For best visual impact, plant in groups (at least 20 bulbs).
• Known for attracting bees, butterflies, and other pollinators, but deer ignore it.
• To be planted in fall.
• No serious pest or disease issues. Keep an eye out for onion white rot, and downy mildew.
• Propagate by seed, sowing seeds in containers with bottom heat when ripe and grow on under glass. Remove offsets in spring and grow on under glass for 2 seasons.
• Allium Unifolium is native to the coastal mountain ranges of California, Oregon, and Baja California.

Many hundreds of Allium species exist, but only a modest few have made a name for themselves as garden plants. The ornamental onions distinguish themselves by their great diversity in color, inflorescence and flowering height. Many species bloom in early summer - just after the spring-flowering period and just before the exuberant full bloom of summer. All species can be used in the border. Certain small species are just perfect for a rock garden, and several lend themselves to naturalizing.
