  • Allium Nigrum or Allium Multibulbosum Nigrum is an heirloom ornamental onion with narrow, green leaves towards the base, on the top of the tall stem forms a semi-spherical or half-globe umbel with many creamy white flowers that are star-shaped with light green centres or ovum.

    Creamy whites with big petals, Allium Nigrum has beautiful blooms with florets of creamy whites. Attractive to gardeners and pollinators, the florets are large and open showing off their beauty in the garden and bringing pollinators like birds, bees and butterflies to the area. Plant in groups or use these delightful blooms in garden flower areas. Great for planting at the back of beds or in borders or in pots or containers and wonderful as a cut flower.

    Genus Allium includes a variety of cultivars which are both useful and beautiful, some of the well-known cultivars includes leeks and onions. Cultivars of the beautiful flowering varieties of Allium are commonly called ornamental onions. Allium plants are perennial geophytes with bulbs. Stalks or scapes, are long, leafless stems which rise from the bulb on which the flowerheads are produced.

    Flowerheads of the Allium are often characterised by multitudes of small blooms, some with very petite petals resulting in an almost pom-pom look. Other blooms are larger in size and have larger petal sizes, and typical flowerheads are spherical or rounded in shape.

    Allium are hardy plants and can tolerate cold weather up to zone 4. Sun-loving, Allium prefers to bask in the sun’s rays all day long and can tolerate some shade. Must be planted in the fall prior to freezing so roots are able to initially set before the coming cold.

    Hardy growers, Allium is tolerant of most soil types and conditions as long as they are well-drained. Drought-resistant Allium is great for adding splashes of colour to the garden scene. Plant bulbs at depths of 2-4 times the diameter of the bulb, usually in the range of 10-15cm.
