Allium Carinatum Subsp Pulchellum Album

This is the rare and exquisite but easily grown pure white form of this valuable, late-flowering plant. Strong flower stems carry graceful loose heads of icy white, bell-shaped flowers, just like an exploding firework display, for two months or more. If you are lucky, in well-drained soil, it will gently self sow and form handsome drifts. RHS AGM winner
