Few Flowered Leek

Few-flowered leek is increasingly present in our wild spaces. It is particularly abundant in wooded areas, and is rapidly taking over our beautiful ancient woodland. It is a perennial bulbous plant that typically blooms between March and May, filling hedgerows with a garlic scent and multiple white flowers. This plant has been resident in the UK since the 1800s, spreading craftily, and quietly gathering pace. Once established, few-flowered leek will smother surrounding vegetation, which has a devastating effect on the local ecosystem.

The smell of the few-flowered leek is its most easily recognised characteristic. All parts of the plant are heavily garlic-scented when crushed.

Why Control Few-Flowered Leek?

Few-flowered leek is an aggressive plant that outcompetes native plants and disrupts the ecosystem. It spreads rapidly through bulbils to form dense mats, particularly in forest and woodland areas and along riverbanks. During early spring, the plant outcompetes native species that are beginning to emerge after the winter, starving them of sunlight and nutrients.

Plants Mistaken for Few-Flowered Leek

Common lookalikes of the invasive few-flowered leek are Wild Garlic, Bluebells and Lily of the Valley. It’s essential to be able to tell these plants apart, because Bluebells and Lily of the Valley are, in fact, toxic if ingested.

Name	Leaf	Flower	Garlic Smell	Toxic
Few-Flowered Leek	Long, narrow, single leaf	One flower & bulbis	Yes	No
Wild Garlic (A. ursinum)	Several, broad leaves	Many flowers	Yes	No
Bluebells	Multiple, narrow leaves	Bell-shaped	No	Yes
Lily of the Valley	Broad paired leaves	Bell-shaped, white	No	Yes

Delicious Invasive Leeks

There’s a particular section of the public who are very happy about the abundance of few-flowered leek. It turns out this highly invasive species is actually very tasty, and those in the know are gathering it enthusiastically for its superb flavour.

There are two varieties of wild leek, both edible and delicious: the three-cornered leek and the few-flowered leek. Both of the wild leek species taste similar to wild garlic, like a particularly strong spring onion. All parts of the plant can be used in cooking; the leaves can be chopped and added to soups and salads, the flowers can be used for garnish, and the bulbs can be used in the same way as garlic or pickled for later use.

It may be delicious, but few-flowered leek is highly invasive and spreads rapidly by self-seeding and producing bulbis. Foraging for this plant must be done carefully and responsibly to avoid further spread in the wild.

Treatment and Control

Manual removal using a fork and pulling out by hand is possible for small infestations. The best time to tackle it is early spring, before it flowers. Smothering the plant with black plastic or mulch can also prove successful, but it must be left in place for an entire growing season. Repeated cutting can also weaken the plant – this is best used in combination with other methods.

Glyphosate-based herbicide is effective against the few-flowered leek. Apply when the leaves are out, before flowering, but note that herbicide is ineffective on dormant bulbs, so repeated applications may be required.

Do not compost the waste. Few-flowered leek is invasive and can re-root from waste material. The waste must be bagged, binned or burnt.
