Is onion weed edible?

Some species referred to as onion weed (e.g., Nothoscordum bivalve) are not true onions/garlic and may be mildly toxic or cause digestive upset. It is generally not recommended for consumption unless positively identified by an expert.

How do I get rid of onion weed?

Manual removal is most effective, requiring careful digging to extract the entire network of bulbs and roots. Smothering with mulch or using specific herbicides are other methods, but persistence is key due to its resilient bulbs.

What's the difference between onion weed and chives?

Chives (Allium schoenoprasum) are a cultivated, edible herb with hollow, cylindrical leaves and a strong onion flavour. Onion weed typically has solid, grass-like leaves, a milder scent, and is a weedy, invasive plant.

Why is it called a 'weed'?

It is called a weed because it grows aggressively where it is not wanted (e.g., gardens, lawns, crops), is difficult to eradicate, and competes with desired plants for resources.
