Bring bold, late-season structure to your garden with Allium × 'Bobblehead' (Ornamental Onion 'Bobblehead'). This upright, clump-forming perennial stands out with oversized, pale lilac flower globes held high above twisting, blue-green foliage for a clean, architectural look.
Plant it where you want strong vertical accents and pollinator activity. The rounded blooms draw butterflies and other beneficial insects, and the flowers also make excellent cuts for fresh arrangements. After bloom, the dried seedheads can be left in place for added texture and seasonal interest.
For best results, grow it in full sun to part shade and give it well-drained soil. Space plants so the foliage can dry after rain, and avoid consistently soggy sites. Once established, it is easy to maintain; you can deadhead for a tidier look or leave stems to dry for decorative seedheads.
Mature plants reach about 30-32 inches tall with a 20-24 inch spread, making it a great choice for borders, mass plantings, and large containers. Its onion-scented foliage is typically unappealing to browsing, so it is a dependable option where deer and rabbits are common.
