These are flower bulb tops, maybe Ornithogalum umbellatum for instance.

I think you hit the nail on the head! Thank you. I don't need to get them out of my flower bed, just the turf. I'll be excited to see them flower.

The lower ones, with the pale stripe, are pretty certainly Ornithogalum umbellatum. It is a terrible spreader and some people grow to hate it for that reason.Top ones may be different since I can't see the stripe.

Other people plant bulbs in grass deliberately, so that it becomes like a flowering meadow. So it's just a matter of what effect you want - the bulbs being in the grass isn't automatically a problem.

Look like digging them up in the turf is the way to go. I like them, but not in my turf. Thank you all for your help. I'm super impressed by this forum!
