The Van Noort package contains 1 Allium bulb size 18/20 for planting 15 cm (6 in) deep and 20 cm (8 in) from neighbouring bulbs. Hardy in Zones 4 to 10, white Allium stipitatum prefers sun, fertile soil, and exceptional drainage. Its starry florets attract insects, while the durable head suits white borders, contemporary gardens, and fresh or dried bouquets. Let the foliage yellow completely before cleanup so the bulb can return strongly.
