Hi, I have a speckled purple plant with yellow stamen that looks a lot like deadly nightshade. The pics I've seen the plant have wide leaves whereas my plant has grassy like leaves. I ask because I have children and don't know whether to be worried or not?

It is not a nightshade.

Those are fritillaries, common name guinea hen/snakes head

Snake's Head Fritillary (Fritillaria meleagris)

Yes, they are fritillaria .

Thank you for your replies. I can let the kids eat them now!

I wouldn't ever encourage any plant that isn't meant to be eaten.

Thanks Pirl, that was a joke! 😂

Whew! You had me very concerned.
