The local name for this species is called Lantern Dendrobium.
In Taiwan, it is one of the easiest dendrobiums to cultivate and to bloom. It is also a good choice for orchid beginners.
Snow and Kim, there are 6 spikes on this plant this year. I also have some similar dend. species, such as farmeri, amabile and densiflorum. My amabile and densiflorum are also spiking recently, maybe they will bloom together next weekend.
