I can't see the flowers clearly, but they're much more likely to be that very invasive form of Allium than snowdrops at this point in the year, and they do sometimes flop over a bit, but to be honest, that patch looks as if something had lain there for a while (fox? cat?). Crush a leaf or two to see if they smell of onions - if they do, its an Allium.

Agree with Bamboo - much too late for snowdrops!

I too agree with Bamboo. They do look very much like wild garlic : Allium ursinum.

Something's definitely been sleeping there.

Best get rid unless you are very fond of them or they will soon be everywhere.

I've added a couple of closer pics. The leaves are not the same as allium. It may well be foxes that have lain on them.

I think your bulbs might be Puschkinia... a nice thing, not very often seen.

Could be Bamboo, we grow them

It's been suggested they're white bluebells!

Not white bluebells Dneicy flower is wrong.

Now you've added the closeups its clear they aren't alliums anyway. They are very pretty.
