I've been babysitting this plant for my sister for four months and it has just about had the biscuit. It is her pride and joy. She picked it up while sailing down the coast (the intercoastal waterway?), kept it growing in a pot of what looks like dirt (as opposed to potting soil) for about two years, gave it to me to babysit and took off to sail down south again. I've never grown it before. I have it with my other plants, under lights, in a warm room. More water, less water seems to make no difference. Fertilizer? Dormant period? Short-lived anyway? She said it had bloomed once.
