Allium caeruleum is an unusual, highly decorative, ornamental type of Allium bulb which typically blooms in late Spring to early Summer.

Producing compact heads of deep, cornflower blue flowers on long wiry stems, the Allium caeruleum, also known as the blue-globe onion, or blue ornamental onion, are perfect for attracting bees, butterflies and other pollinating insects in the garden.

These perennial bulbs are best suited for well-drained, yet fertile soil and, with their starry-blue flowers which form compact, rounded clusters in early summer, they grow best when positioned in a full-sun area of the garden, such as a sunny border. When sited in the borders, it will make a beautiful and attractive display once flowered.

Typically, the narrow leaves will wither and die back before the beautiful bloom appears, so introduce these bulbs with other plants which will help disguise the faded foliage.

This Allium flowers in June-July and can grow to 60cm/24in, lasting brilliantly in the garden or within a vase when cut. With new bulbs, plant them around 2-4in deep within the ground.
