Allium atropurpureum is an heirloom variety with deep purple-red flowers. Blooming late spring to early summer on sturdy 2-to-3-foot stems, each half-globe blossom holds dozens of star-shaped florets buzzing with bees and butterflies. Seed heads remain in the garden, adding interest long after flowers fade. An excellent cut flower, both fresh and dried. Bulbs will multiply and spread over time.
To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low
temperatures; the lower the zone number the colder the winter.
If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will
survive the winter temperatures in your area.
If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack
of freezing winter temperatures do not provide a time for winter dormancy (rest).
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.
