Cultivars of the beautiful flowering varieties of Allium are commonly called ornamental onions. Allium plants are perennial geophytes with bulbs.

Flowerheads of the Allium are often characterised by multitudes of small blooms, some with very petite petals resulting in an almost pompom 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
