As gardeners, we gravitate to the strange and usual offerings that will set our gardens apart! So Nature Hills is sure you'll love the unique Sphaerocephalon Allium (Allium 'Sphaerocephalon') the purplish-maroonish-violet oval blooms that are tightly packed drumsticks atop slender green stem that wave in the breeze!
The upright grassy foliage is hollow like its onion family relations, but won’t make your eyes water! You may notice a slight onion scent when the foliage is cut, but that won't stop the bees, and butterflies, and occasional hummingbirds from seeking out these nectar-rich blooms!
Also known as Drumstick Allium or Round-Headed Alliums, these unique selections are lovely textural and colorful accents throughout USDA growing zones 4-8 and form naturalizing clumps 14-16 inches tall.
Planting and Application:
Sphaerocephalon Allium is a highly Ornamental Onion that are must haves for a quirky pollinator or Cut Flower garden! You'll enjoy unique bouquets and loads of pollinators anywhere you do choose to plant these whimsical late-spring to early summer flowering bulbs! These are a must have for the Children's Garden, in a modern Cottage and Perennial border, and melds well into both informal and formal settings.
Alliums are space-saving little bundles of drama and look fantastic in planters as thrillers and vertical height! Both as an addition to a mixed container garden, or as the feature planting in groupings with a spiller planted around the edges. The grassy foliage looks great as edging and seasonal facer plants along your garden bed and border edges!

#ProPlantTips for Care:
You'll have the most blooms in full sun when grown in cooler climates and appreciating partial shade (afternoon shade) in hot climates, any rich, well-drained soil is perfect for Allium. 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. Despite being a member of the Onion family, there is no Onion smell unless the foliage is broken or crushed. Deadhead to remove spent blooms or try this trick - spray paint the dried seed heads any color you choose for unique garden décor for the rest of the summer and fall! Deer, rodents, squirrels, pests, and diseases usually don't bother these easy-going flowering perennial bulbs!
- Full Sun For Strongest Growth
- Well-Drained Soil Of Any Kind
- Moderate Moisture Needs
- Deadhead After Flowers Fade & Prune Mounds After Leaves Yellow
- Squirrels, Rodents & Deer Seldom Bother These Plants
