Hi

I was recently given a small plant which I am trying to identify, here's
what I can tell you.

It flowers yellow in either spring or summer

It's quite small, I think it's a slow grower and gets fuller rather than
taller

Evergreen, quite healthy looking now in the UK

The foliage (mid green) is spiky from the ground and quite 'hard' I presume,
as it stands up (doesn't wilt), It look's a little bit like a human hand
sticking out of the ground.

Any ideas ?
