Allium ‘Purple Sensation’

Also called ‘Allium aflatunenense’ has vivid rosy-purple, 4 to 5″ globes of tall flowers that appear in late sunny border. This is a perennial that grows to 36″, with short basal leaves dying down by flowering time. There’s no better allium for bridging the season from spring bulbs to early summer perennials. Returns year after year. Allium 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 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! Position where other plants will help to hide their sometimes-untidy foliage. Excellent for use as cut or dried flowers. Attracts butterflies, too.
