I don't recognise it sorry . but I will have a browse and see if I can find it.

Are you sure it's a fern?
I've got a vague memory of a plant that looks like this but I just can't recall what it was or where I saw it. The only, slight inkling I've got is that I was researching plants grown from spice seeds

I think he should go back to the shop. They may have another one that has a name tag.
Thanks anyway.

It looks like a fern a florist may use. I hope the shop can help him.

I have advised him to visit the Fern collection at the Chelsea Physic Garden in London which is near where he lives.
