|Phalaenopsis appendiculata at the Fuqua Orchid Center|
Though it appears huge in the photo, our Phalaenopsis appendiculata is actually about 2" x 2". I have watched with increasing admiration as it has produced flowers in succession, month after month. But what I find totally charming are those undulating leaf margins.
High humidity and hot temperatures are the key to growing Phalaenopsis appendiculata. Although we grow ours slightly drier and cooler, Dr. Tsuneo Ikedo, on his fantastic Phalaenopsis Species website, recommends 85% relative humidity; 73º at night and 89.6º as the daytime high temperature. That's lowland tropical.
