It is an Aroid of some description, never can remember the name of the one everyone seems to grow these days.

With that snake skin stalk it could be some sort of sauromatum. Maybe an S. venosum otherwise known as the voodoo lily?

That's the one, the name always escapes me. There are Arisaema with mottled stalks like that as well.

Yes, Sauromatum venosum. It has several leaflets in a crescent formation which is what we grow it for.
