Is this a weed or self set plant?

I wonder if anyone has any idea what these are? They are a single shoot with a tiny bulb. I’ve never had them before and want to remove them but wondered if they could be self set from something I’m already growing? I’ve planted lots of new stuff in the last year, including a lot of alliums. Any ideas? Thank you.

I'd say it's very likely they are allium seedlings if the parent plants are in that area. It will probably take a couple of years for them to grow to flowering size.
You could always pot them up and grow them on elsewhere if you need the space for other plants.

Crush a leaf and sniff it. It'll be obvious if it's allium (onion smell).

I have them all over, is my job to collect some for potting today!-  definitely self sown allium!

Thank you all so much. That’s brilliant advice and I will pot them up over the next few days. Brilliant! Cindy.
