At Japanese Knotweed Expert, we don’t just specialise in Japanese Knotweed — we’re your trusted experts in the identification, management, and eradication of all invasive plant species across the UK (including three-cornered garlic).
Three-Cornered Garlic (Allium triquetrum) is a fast-spreading, non-native plant that has become increasingly common in UK gardens, particularly in milder regions. While it may look attractive with its white, bell-shaped flowers and garlicky aroma, it’s a serious threat to native biodiversity.
Three-Cornered Garlic is classified as an invasive, non-native species due to:
Aggressive Growth: Spreads rapidly through underground bulbs and self-seeding.
Outcompetes Native Plants: Forms dense ground cover that blocks light and crowds out local flora.
Difficult to Remove: Even small fragments of bulbs left in the soil can result in re-growth.
We recently conducted a specialist invasive species survey in Bury, where a homeowner’s soft landscaping was completely overrun by Three-Cornered Garlic. Left unmanaged, this plant would have continued to dominate the garden and spread to neighbouring properties.
Thanks to our expert assessment and tailored removal plan, the infestation was identified early and effective control measures were implemented.
If you suspect Three-Cornered Garlic or any other invasive species in your garden or grounds, don’t delay. Our qualified specialists can provide a full site inspection and effective treatment plan.
