These orchids, officially classified as Dendrobium Phalaenanthe have a similar flower structure to the moth orchid. These are great orchids for starting orchids since they are very tolerant of mistakes and have high ranges of care. Dendrobium Phalaenopsis orchids will bloom anywhere from having 5 flower spikes to having around 20 in a mature plant. Since they are from climates that have warm weather year-round, such as northeastern Australia and Southeast Asia, they don’t experience a winter drop in temperatures. They also can’t grow well under temperatures under 55° F or 10° C and stay mainly around the 80’s F or 32° C. In its natural habitat, the Dendrobium Phalaenopsis orchid reblooms around 3 times a year because it is an evergreen plant. Most Den Phal’s leaves do not fall off, even though some might. Den Phals (unlike Phalaenopsis orchids) prefer to dry out completely before watering again.
