About
Large, architectural perennials up to 1.5m tall and 1m wide, with large, silvery grey-green leaves. Green, scaly buds open to thistle-like purple flowers in summer and autumn. Grown for their edible flower buds, but ornamental enough for the flower garden. Many varieties of globe artichokes are available, varying in plant and bud size and bud colour.
