Allium

Distinctive, spherical shapes for playful perennial gardens

Alliums, otherwise known as ornamental onions, produce showy, globe-shaped flowerheads made up of many small and delicate stand-alone blooms. Bees and butterflies visit allium often, making them a great choice for sitting near veggie beds, where they'll also help to repel deer. At home in rock gardens, walkway borders, and containers, most use these cold-hardy perennials to add lively contrast to otherwise dull-looking beds.
