Allium

An ornamental onion with a globe of flowers
Allium
This onion is prized not for its taste, but for the abundance of its flowers. Each long and stately stem of allium finishes a globe of tiny petals.

Caring for Alliums

  • Provide a clean vase and clean water at room temperature.
  • Trim the stem diagonally with a knife.
  • Remove the leaves so they’re not hanging in the water.
  • Add cut flower food to the water.
  • Refresh the vase water every five days and top it up in between.
  • Avoid full sun, draughts, heaters and bowls of fruit.
  • It's easy to dry the globe of flowers to enjoy allium for longer.

Colours and shapes

There are some 300 different varietes of allium in total, and almost all of them bloom in the summer. The ball of flowers is greater or smaller depending on the variety, and colours range from white to purple or blue.

Alliums have a long vase life, and they're also easy to dry, making them a sustainable flower choice. It's only when the stems are cut that the plant releases its characteristic smell of scallions, so plunge them in water immediately after trimming to minimise their pungency. 

Symbolism

Onions are have many traditional uses, especially the strongly-scented varieties. Cut in half, or hung up in a string, they are said to keep away bad luck, sickness and even witches. Allium victorialis, also known as the Alpine leek, represents victory. In Germany it's even known as 'the ordinary man’s armour'.

Origin

Alliums grow in temperate regions in the northern hemisphere. The Romans used the word ‘allium’ to refer to garlic, but it has become the family name for all onion crops, including chives and leeks. Allium Giganteum is the largest variety of the allium flower, growing up to 1.5 metres tall and with purple flower clusters that can measure an extraordinary 15 cm across.
