This proprietary eCommerce software prevents the shipment of a restricted plant to each state. The Plant Sentry system includes a shipment certification program. The Plant Sentry Compliance Officer works closely with NatureHills.com and each nursery or fulfillment center to ensure only compliant plants are sold to customers.

Big bold blooms! The Giganeum Allium (Allium 'Giganeum') is an enormous densely and evenly packed flower cluster with round florets that look like gorgeous purple stars! Resembling fireworks or an explosion of purple sparks, these late spring to early summer blossoms can reach 5 inches of nearly perfectly round flowers!

A member of the Onion family, these spring-flowering Ornamental Onions are packed with starry florets that resemble shooting stars! The green foliage and strong, sturdy hollow stems support these lovely blooms and attract loads of pollinators and hummingbirds! Plant a few extra bulbs for these winged visitors and for yourself to create amazing floral bouquets!

Giganeum Alliums are hardy and adaptable throughout USDA growing zones 5 to 8, and can reach a 2-3 foot height in the garden and bloom for several weeks, leaving behind unique seed heads for summer interest! Deer and rodents rarely bother these bulbs or plants, and they're very hardy without any pests or diseases.

Planting and Application:

These are fantastic cut flower garden blossoms that will add an amazing wow factor to your bouquets! Allium are must-haves for honeybees, butterflies, and beneficial insects so plant them in your pollinator garden as well! Add round pops of color to Cottage gardens, perennial beds, and bulb gardens mixed with other plants and spring and summer flowering bulb plants! Allium is an absolute must for Rock gardens, Cottage gardens, or gardens where they spark the imagination of kids!

Giganeum Allium is certainly a head-turner in the landscape, especially in formal plantings, in groupings, and en masse! Sized perfectly for large and small gardens, adding their high-impact color and appearance to make up for their space-saving clump size. Perfect focal points and height for large container gardens and mixed planters, these flowering bulbs mix and mingle wonderfully among other plants.

  • Huge Perfectly Round Purple Flower Clusters
  • Green Upright Oniony Foliage
  • Bold Vertical Interest & Pollinator-Friendly
  • Incredible Floral Arrangement Accents
  • Great in Containers, Back Border, Vertical Interest & Specimens

#ProPlantTips for Care:

These showy and whimsical Alliums reach their full potential in full sun and fast-draining soil. Fall-planted bulbs need moderate moisture needs. Any soil type is suitable so long as it is not soggy and add bulb fertilizer to each hole for best results. Their blooms last for weeks and they naturalize and spread over time unless you deadhead after the flowers fade. Deadhead after flowers fade, but let the leaves remain so they can make food for the bulb and next year's flowers! Once the foliage yellows in the summer or fall, you can then prune it to the ground.

  • Full Sun For Strongest Growth
  • Well-Drained Soil
  • Moderate Moisture Needs
  • Deadhead After Flowers Fade & Prune Mounds After Leaves Yellow
  • Deer Seldom Bother Them

Giganeum Allium is a huge high-impact purple bloomer that will add whimsy to your landscape! Order your own heavenly deep purple blooms and high-quality bulbs today from Nature Hills and we'll ship them to your doorstep at the proper fall-planting time in your growing zone!
