What is this called

I think it's called 'Asparagus Fern', Blodyn.

Asparagus setaceous, wish I could say I had a lot of success with mine, but that would be untrue...I loved it though...Your fern looks like it's growing nicely...congrats!

Watch out for the thorns Blodyn. It is an asparagus, I had one in the garden and it grew into a prolific shrub, but took it away later on, as I hurt myself many a time on the spikes. Once bitten, twice shy I say. I garden for my pleasure and not to be hurt, lol.

Thanks all three.
It does have little thorns - I'll have to be careful of it I think Marguerite !
