Collection: Allium Bulbs for Sale

Alliums, also known as ornamental onions, add architectural drama to any border with their spherical flower heads held high on tall stems. They bridge the gap between spring bulbs and summer perennials, flowering in late spring and early summer, and they're a magnet for bees.

Plant allium bulbs in autumn, around three times their own depth, in a sunny spot with well-drained soil. The dried seed heads look great left standing into autumn.
