I purchased this as Arisaema triphyllum, but not sure that is what it is.

Bob, that is a gorgeous plant! I'm not real familiar with Arisaema so hopefully someone who grows them will come along to identify your plant! For comparison, check out some of these at the aroid.org website:

It looks like Arisaema heterophyllum, does it make leaves in a horseshoe shape? A young plant may not show the true habit.

Arisaema tortuosum is another possibility, it grows very tall but the spathe usually grows above the leaves. The stems can be spotted or not, the spadix can be dark or green.

A fuller view would help.

It was the only picture I took before something ate the top off. It was about 3 foot tall then add another foot for spadix with dark brown spotted stem. From pictures I've seen so far I'm leaning toward tortuosum.

Well I'm going to move this to Tortuosum.

You know best what it looked like in reality Bob, I would agree with that.
