Allium caesium

Growing Alliums: The Allium family includes onions, leeks, and chives, but the ornamental varieties have become increasingly popular with gardeners thanks to their unique beauty. Globe-shaped flower clusters float above thin, elegant flower stalks. Allium bulbs are planted in fall, and bloom in late spring, bridging the gap nicely between spring-blooming flower bulbs and early summer perennials, such as Peonies, Poppies, and Salvia. For a pop of color and texture, plant Alliums in groups, or plant among perennials. Within their hardiness zones, they will return year after year and may naturalize and spread over time. Leave spent flowers standing to add interesting texture to your garden through the fall and winter.
