There are many varieties of phalaenopsis orchids on show at Hawaii Tropical Botanical Garden. This one is Phalaenopsis (ChianXen Queen x Diamond Beauty).
There are so many orchid hybrids, with subtle variations, that it can be difficult to identify them. However, at the garden, I’ve found that if I root around at the base of the plant I often find a name tag sticking out of the dirt, and when it comes to identification I’ll take all the help I can get.
