The Van Noort package contains 1 Allium bulb size 20/+ for planting 10 cm (4 in) deep and apart. Hardy in Zones 4 to 10, this compact purple ornamental onion prefers sun, fertile soil, and exceptional drainage. Its dense globe attracts insects, is generally deer resistant, and remains graphic after bloom. Moderate height particularly suits borders, small beds, large pots, and fresh or dried bouquets where the head stays easy to admire closely. Its dried sphere extends structural interest into early summer.
