Allium 'Caeruleum'

Allium 'Caeruleum' is a graceful ornamental onion with a cool-toned elegance, blooming in June–July with airy, rounded flower heads in a clear sky-blue shade – a rare colour among alliums. Each flower globe consists of numerous small, star-shaped florets, tightly packed into a harmonious, spherical shape. These are borne on slender stems about 50 cm tall, rising delicately above the narrow blue-green foliage, which fades back discreetly during flowering.

'Caeruleum' is ideal for adding a sense of lightness and vertical rhythm to perennial borders, especially when combined with silvery foliage or soft lavender and white hues. A refined and balanced variety that brings a touch of cool clarity to the early summer garden.
