Allium 'Azureum'

Allium 'Azureum' blue! Bright periwinkle flowers bloom in early summer and develop into large, impressive clumps over time. True blue is hard to find among flowers, but look no further! Allium caeruleum has a deep, clear, stunning blue color. Each bloom is comprised of dozens of starry florets accented with darker blue midveins. 'Azureum' Alliums are loved by bees, butterflies, and helpful pollinators. Alliums are deer resistant and easy to grow in well-drained soil in full sun to partial shade. Water well after planting. A great ornamental value in the landscape and amazing cut or dried flowers. They return year after year. Alliums are bulbous herbaceous perennials with an onion or garlic scent, linear, strap-shaped or cylindrical basal leaves, and star-shaped or bell-shaped flowers in an umbel on a leafless stem.

Alliums: Easily grown in average, medium wet, well-drained soils in full sun. Best sited in locations sheltered from strong winds. Leaves will wither and disappear from the garden shortly after bloom. Mature bulbs may be dug up in fall, divided and replanted to increase the size of a planting. Alliums, or ornamental onions, are easy to grow bulbs that are increasing in popularity. They look wonderful in cut bouquets and make a unique accent in any perennial border or bed. If you have problems with deer or rodents, Alliums are an excellent choice as they find them distasteful! The position where other plants will help to hide their sometimes-untidy foliage. Excellent for use as a cut or dried flowers. Attracts butterflies, too.
