It is either P. cookianum (now known as P. colensoi) or a hybrid, as P. tenax has rigidly upright leaves. As to which cultivar (if any), I have no idea :-) There is nothing very distinguishing about this one, while the brightly colored or variegated ones are easier to identify.

Thank you.

I hate to say this, but that is exactly the answer I was expecting, based on what I had read on-line.
