Nice photo Henry. I notice you're growing them in a pot. How do you overwinter? Might be atropurpurea.

These were just left outside in a group of pots.
We bunch pots of hosta, carex, sedge, and pinellia together in a somewhat protected spot.
We are actually a Zone 7 here and have grown several 8's w/ deep mulch.

Really a nice looking bloom and tough plants. The colors on your spathe is about the nicest I've seen searching the web.

Thanks Evan!
