Imagine your beds and borders decorated with the floral equivalent of the sparkler firework. Allium caeruleum is just that plant, with dainty, star-shaped, pale blue flowers that seem to explode from each stem in a ball of firework twinkle. It is perfect for the middle of beds and borders, and also looks lovely in containers, attracting pollinators, such as bees, to wherever you plant it. These bulbs will burst into flower in the early summer, enjoying full sun and ready to catch everyone's eye. They are also beautiful as parts of vase or floral arrangements and can be dried for use as decorations. Caeruleum has been awarded the Royal Horticultural Society's Award of Garden Merit.
Ideal as cut or dry flower.

Alliums will grow in a wide range of soils provided there is good drainage. They like sunshine but the flowers will last longer in partial shade. Valuable for planting in groups in borders or for naturalising (leaving in for flowers year after year). Excellent, long lasting cut flower. Late planting in autumn prevents bulbs from making early shoots which can be damaged by frost. Plant taller varieties to the rear of borders. Flowers can be used for dried arrangements
