Allium acuminatum

What to Eat

Edible parts: Seeds, Flowers, Leaves, Roots, Bulb

The bulb, which is typically 10–15mm wide, can be eaten raw or cooked and is best in spring and early summer. It has a strong onion flavour and can be roasted, sautéed, or added to soups and stews. The leaves are edible raw or cooked and used as a relish or seasoning much like chives, though they are best finely chopped to avoid stringiness. Flowers can be eaten raw as a garnish on salads. Seed heads can be placed in hot ashes for a few minutes, then the seeds extracted and eaten. The flavour is excellent, though the small bulb size limits overall yield.

How to Identify

An onion family plant with a bulb. It grows to 30 cm tall and spreads to 8 cm across. The leaves are 12 mm long. The leaves taper to the tip. The bulb is 10-15 mm wide. The flowers are pinkish purple. They are urn shaped.

How to Grow

Prefers a sunny position in a light well-drained soil. The bulbs tend to rot when grown in cool wet climates, even if they are given sharp drainage. This species is best in a cold frame and given a dry summer rest. The bulbs should be planted fairly deeply. Most members of this genus are intolerant of competition from other growing plants. Grows well with most plants, especially roses, carrots, beet and chamomile, but it inhibits the growth of legumes. This plant is a bad companion for alfalfa, each species negatively affecting the other. Members of this genus are rarely if ever troubled by browsing deer.

Propagation: Sow seed in spring in a cold frame. Prick out seedlings into individual pots when large enough to handle — placing three per pot will produce clumps more quickly. Grow on in a greenhouse through at least the first winter, then plant out into permanent positions in spring once growing vigorously. Divide in spring. Plants can be divided successfully at any point during the growing season and divisions can be planted straight out into permanent positions if needed.

Medicinal Uses

No specific medicinal uses have been recorded for this species, but members of this genus are generally considered healthy dietary additions. They contain sulphur compounds responsible for their onion flavour, and regular consumption is thought to help reduce blood cholesterol levels, act as a tonic to the digestive system, and support the circulatory system.

Other Uses

The growing plant is said to repel insects and moles. The bulbs can also be rubbed directly on the skin as an insect repellent.

Allium acuminatum, also known as the tapertip onion or Hooker's onion, is a species in the genus Allium native to North America.

Notes

There are about 300-700 Allium species. Most species of Allium are edible (Flora of China). All alliums are edible but they may not all be worth eating! They have also been put in the family Alliaceae.
