Allium triquetrum

Fill out a space and supress weeds with this effective ground-covering Allium triquetrum. Flowering in spring with elegant white blooms, Three-cornered Leek is a good plant for adding interest to a tricky planting area which is otherwise bare, such as along hedges and under trees. If you’re looking to attract pollinators to the garden or have a designated wild area on your patch, this allium provides plenty of nectar-rich blooms that bees will love!

The bulbs of Allium triquetrum multiply over the years and the flowers also set seed, meaning this variety naturalises quickly. Spreading to form dense clumps over time, it fills an empty space with effective leaf coverage as well as more and more blooms each spring. Allium triquetrum can’t be planted in the wild, but you can let it loose in your garden where there’s room for it to run riot!

A. triquetrum has various common names, ranging from triquetrous leek to three-cornered leek and three-cornered garlic.

⚠️ Please note: Allium triquetrum spreads freely and is considered invasive in some countries, including the UK. It should not be planted in any space where it can spread into the wild.
