Allium schubertii
ornamental onion
Giant-sized flowerheads (to 30cm across) create a starburst-like effect, which tops the compact stems of this ornamental onion in summer. These heads are excellent for adding to both fresh and dried floral arrangements, and look particularly effective when they are sprayed with silver or gold (after being dried) and used as Christmas decorations. Keep in mind that it is quite normal for the strap-shaped foliage of Allium schubertii to die back before the flowers start to emerge.
How to care for Allium schubertii:
Allium bulbs are easy to grow in a sunny spot with freely drained soil, or a good quality potting compost. Ideally they should be planted in September or October, but could also be planted in early November in milder regions. While keeping the size of the flowerhead in mind and avoiding overcrowding, dig holes roughly three times as deep as the diameter of the bulb and place them at the base, pointy side up before gently infilling and watering to settle them in. In early spring, as growth begins, apply a balanced, slow-release fertiliser, and allow the plants to die back naturally and completely before tidying away.
