I might be being a bit thick here, but don't bluebells have flowers? 🤓
Yes, in a month or two depending on your local climate (although I'm hoping the little ones in my pic are too small to flower). They self-seed so deadhead promptly if you don't want the little blighters all over the place. They also multiply underground very quickly so you might want to think about digging them out.

That first pic could be an iris foetidissima. They're a woodland plant and they grow like weeds in my garden.
