Hawaiian Phalaenopsis Orchid Plant Grow Hawaii My name comes from the classic Greek and means "moth-like." I bloom up to a dozen flowers on a graceful arch which give the illusion of butterflies in flight. My flowers last up to 2 months, and the succession of blooms on a single plant may produce flowers for more than half the year. I have been told that I'm among the loveliest of all the spray orchids. GROWING INSTRUCTIONS: Please plant in fir bark or asmunda, and keep moist never soggy. I prefer 60 to 70 percent humidity and temperatures of 65F at night and 80F during the day. I'm a shade-loving plant and happiest with 50 percent shade. Never water me at night or I'll die. Feed me with a liquid fertilizer weekly. An east window is ideal.
