About Allium Bulbs (Giant) - Giganteum

Allium

Seed Type Bulb
Plant Type Giant
Also known as Giant Onion, Ornamental Onion, Flowering Onion

The majestic and stunning Giganteum allium is perhaps the tallest available allium on the market, with blooms the size of a softball, it grows up to 5 feet tall. Giganteum is a fall planted flower bulb that blooms from late spring into early summer. Like all alliums, Giganteum is best planted in clumps of 10 or more bulbs to create a stunning and unusual effect in the late spring garden. Giganteum alliums should be planted in a sheltered location to protect the blooms from strong winds. Giganteum allium is excellent for either cut flower or dried flower arrangements.
