General information about Onion (Allium):
The genus Onion (Allium) includes many vegetables but also plenty of ornamental species. Most Onions like a sunny position in a good, slightly alkaline soil. In the winter the bulbs can rot if they are too wet. If you plant your Onion in the autumn, cover them for the first winter with a layer of leaves. With a lot of the species the leaves will dye back during the flowering period. Remember this when planting and camouflage the gaps with, for instant, ornamental grasses. Some of the smaller species of Onion can spread vigorously. These are good for in a wild garden. Onion flowers attract lots of insects and are also good cut flowers. When the tall species flower on the nursery, they sometimes are too tall to ship out. We could cut them back, but then you loss that years flower. Best to order early or contact us first.
