Allium cristophii is pure garden theatre — bold, architectural, and star-studded with metallic shimmer. Also known as Allium albopilosum, this heirloom variety is beloved for its enormous, airy flower heads made up of silvery-lilac star-shaped florets. Each globe can reach 20–25cm across, floating above the border on sturdy stems like fireworks frozen in bloom. It’s a spectacular structural element for cut flower growers, and a late-spring statement piece in any border or pot.
 
When to Plant: September – November 
Plant in autumn, giving roots time to establish before the ground freezes. Like all alliums, cristophii needs excellent drainage — think sunny, free-draining beds or raised planters.

How to Plant Allium cristophii:
Plant bulbs 10–15cm deep and 15–20cm apart. They look best in bold groups and drift-style plantings. Water in well and forget about them — they're drought-tolerant once established. Foliage dies back before flowers appear, so plant alongside low-growing companions to cover the base.
