Allium is the Latin name for the group of plants better known as onions. There are actually over 700 different species of Allium, many of which are fabulously ornamental, but all can be identified by the characteristic onion smell of their bulbs and leaves.
They often make great cut flowers, and many varieties can also be dried for lasting displays. The dried seed heads of many Alliums will also persist in the garden, proving continuous decorative interest into autumn and winter.
They are generally low maintenance and easy to grow from seed although for some of the larger bulbing varieties they might take a long time to mature and flower. Happily, many of the most attractive ornamental types can be bought as bulbs, which only need to be planted and they’re ready to provide spectacular display for years to come.
Even the edible types like chives, leeks, onions and garlic will produce beautiful flowering displays if allowed to grow on and flower.
