ALLIUM

This genus of around 700 species of bulbous perennials and biennials includes many familiar plants such as the onion, leek, chive, garlic, and ornamental onion. Allium is the type genus for its family, the Allianceae, and occurs in dry areas of the Northern Hemisphere. The foliage may be fine and grassy, strappy, or hollow and tubular. The flowers are generally borne in rounded heads stop long stems, and are often brightly colored. Many species are famed for their taste and pungency, and form vital ingredients in the world's cuisines. Some, especially garlic, have a long history in herbal medicine and folklore, and the ornamental species are not without an air of mystery, too. In Europea traditions Allium moly was thought to be a protection against demons, and Homer attributed to it magical properties that allowed Ulysses to enter Circe's lair.

CULTIVATION

Most  alliums thrive in fairly light soil in a sunny well-drained position. Ample water is mportant during foliage development and flowering but thereafter the plants can be allowed to dry oll. Propagate by gathering offsets and bulbils or from seed.

Top Tip

Don't worry that by planting garlic or onion species in the garden their distinctive scent will soon take over. The pungent aroma is usually only noticeable when the leaves are crushed or bruised.
