Mine bloom in spring. Yours may not be mature enough to bloom yet. Some take a year or so growth to bloom. I've found that each one has it's own personality. These are tropical epiphytes that grow on trees, so filtered sun, fast draining medium, and they do like to be crowded. I use a cactus mix with mine, but any coarse, humusy mix would be good. I feed with bloom food in spring (March), then switch to a balanced food after bloom, until Oct., then let them go dormant for the winter.. That is the So. Cal. schedule for feeding. I posted my NOID pink in the blooming thread. That one, the one behind it, and my E. oxypetalum were all stem cuttings that bloomed the first year. The purchased leaf cuttings all took at least two years to bloom.
