Allium cyaneum – ​This is a sweet, small ornamental onion with deep blue globes poking above the fine grass-like foliage. They bloom early summer opening from white buds that are reminiscent of miniature exploding fireworks. Sit in sun planted in well-drained soil. Not a weedy species we cannot understand why it is not more often seen. Allium cyaneum is small enough for a trough and lovely in the rock garden or en masse at the front of the full sun border. If ordered in autumn your Allium will arrive as dormant potted bulbs.
