I grow cryptostephanus haemanthoides which i brought back from Tanzania...it seems to be more or less evergreen, and seems to like paramongaia like potting mix...well drained humus rich soil with lots of aquarium grit and pieces of bark added, and lots of watering and liquid organic feeding while in full growth in summer, and produces alot of offsets.
it has not yet flowered, but was identified as haemanthoides by an IBS member based on photographs of leaves and bulbs/roots...
