Allium triquetrum

Allium triquetrum is a flowering plant species in the Amaryllidaceae family. It is commonly known as three-cornered leek or onion weed. This bulbous perennial is native to the Mediterranean Basin, but it has been introduced to other parts of the world, including North America, Australia, New Zealand, and the British Isles.

Description

Allium triquetrum is characterized by its triangular stem and bell-shaped white flowers. The plant typically grows to a height of 17-45 cm. The leaves are linear and flat, measuring up to 15 mm wide. The flowers, which bloom from April to May, are borne in clusters of 4-19 and have a strong onion-like scent when crushed.

Distribution and Habitat

Allium triquetrum is native to the Mediterranean Basin, but it has been introduced to other parts of the world. In its native range, it is commonly found in damp woods, hedgerows, and on river banks. In areas where it has been introduced, it often becomes invasive, outcompeting native plants for resources.

Cultivation and Uses

Allium triquetrum is often grown as an ornamental plant for its attractive flowers. However, it can become invasive if not properly managed. The plant is also edible, with a flavor similar to garlic or onion. It can be used in a variety of culinary applications, including salads, soups, and stir-fries.

Invasive Species

In regions where Allium triquetrum has been introduced, it can become a problematic invasive species. It is capable of rapidly spreading and outcompeting native plants for resources. In some areas, efforts are being made to control its spread and mitigate its impact on local ecosystems.
