Flower Bulb: Allium
Allium mixes well with other hardy perennials with its unique flowers and bright colours
The striking blooms on the ornamental onion are real eye-catchers in the garden. They come in lots of different varieties too. Ornamental onions (Allium) like a sunny spot but will also thrive in part shade. The stately allium grows tall, sturdy stems and just adds that bit extra to any garden. Allium flowers also attract lots of butterflies and bees to the garden. The allium, as a cut flower in a hand-picked mixed bouquet, will also look spectacular in your home!
Allium originated in Europe, Asia and the Middle-East, where they can be found growing wild. The Latin ‘Allium’ actually means ‘sharpness’… referring to the flavour of onion in lots of recipes, but the name Allium has acquired various meanings throughout the centuries.
Ancient Egyptians considered the layers of an onion to be a symbol of eternity and they are often pictured in hieroglyphics on gravestones. It was the Romans who gave the Allium onion, or leek European connections. In Victorian times they were thought to bring luck and prosperity.
Alliums mix wonderfully well with other flowering bulbs like the Amaryllis (Hippeastrum), ornithogalum, lilies and others. Plant your allium bulbs in the autumn in a sunny spot in the garden for a spectacular show in spring and summer!

The allium family
The number of members in the allium family is pretty big with hundreds of varieties, including the edibles - onion, shallot, garlic, chives and leek. There is an even larger group that are show-stoppers in our garden. It’s really quite amazing just how many different shapes you can find in the Allium family! There are some truly huge blooms among them, as well as smaller ones with very delicate little flowers.
