Hi Sheryl, they do like a bit of coolness, and a bright, indirect light. They propagate readily but different from African violets, in that you cut the leaf, if you have the space you cut the leaf along the stem in several places and lay it on the surface of a pot, then wherever its touching soil it will grow babies! (during this process they need almost daily misting, so its a bit of a project but very rewarding!) Then each leaf as it grows sprouts 10 - 20 blooms over its lifetime (so from the plants that I've shown photos of, I've had almost steady blooming for a year!) Very rewarding in that sense, and the blooms are striking, so when people visit they always ask "what is that?" "Are those real?" Its funny how many people have asked if they're fake plants
Cheers
Greg
