Hippeastrum papilio

It has been posted here before I believe that the clone that is most widespread in the trade is evergreen but that wild forms of H papilio have a dormancy. I seem to recall that there was also a suggestion that the common cultivar was not pure H papilio??

Mine is most definitely evergreen, or tries to be. It was in leaf all
summer, it's in leaf now, and despite being kept quite cold (or possibly
because if it) it seems to be putting out new growth.
