Allium 'Haarlem Superglobe'

Also known as: Information to be completed

Hybrid group of perennial, bulbous plants, producing densely-packed spherical heads of star-shaped flowers, in shades of pink, purple or white, on straight stems to 70cm tall in May and June, above short-lived, mid-green leaves. The foliage is often wilting and turning brown when the flowers appear, and for best visual effect, the bulbs should be sited so that adjacent plants can grow to conceal the leaves as they die back. The flowers are extremely attractive to bees and other pollinating insects, making the plant a wonderful addition to a wildlife garden.

Watering

Moist soil during active growth, then reduce watering after foliage yellows

Fertilizing

Light bulb fertilizer at emergence and again after flowering

Pruning

No pruning required, other than to remove old flowered stems and foliage

Propagation

Propagate by offsets to obtain plants the same as the mother bulb, which can be carefully detached by lifting the bulb after flowering has finished. See bulb propagation. Propagation by seed may not produce plants that are true, as this is a hybrid plant

Growing

Easy to grow in full sun and a fertile well-drained soil. It is best to grow in containers where garden soil is heavy clay and prone to saturation over winter. See allium cultivation
