I assume that I have P. esseriana - they were obtained anonymously,
but look like all pictures of the plant.
Mine flower in mid-Winter in an ordinary British cool greenhouse
(temperatures down to 45F/8C). Sometimes I have trouble with
botrytis mould attacking the rosettes in Winter, but detached
leaves easily produce more plants. Indeed the plane sometimes
seems intentionally to eject leaves from the centre of the
rosette.
