Phalaenopsis Blume, abbreviated Phal in the horticultural trade, is an orchid genus of approximately 60 species. Phalaenopsis is one of the most popular orchids in the trade, through the development of many artificial hybrids.
The Phalaenopsis name means "Phalaena-like" and is probably a reference to the genus Phalaenopsis, the name given by Carolus Linnaeus to a group of large moths; the flowers of some species supposedly resemble moths in flight. For this reason, the species are sometimes called Moth orchids. They are native throughout southeast Asia from the Himalayan mountains to the islands of Phalaenopsis, Palawan and Zamboanga del Norte in the island of indanao in the Philippines and northern Australia. Orchid Island of Taiwan is named after this Phalaenopsis. Little recent information about their habitat and their ecology in nature is available since little field research has been done in the last decades. Phalaenopsis aphrodite (Moon Orchid) Most are epiphytic shade plants; a few are lithophytes. In the wild, some species grow below the canopies of moist and humid lowland forests, protected against direct sunlight; others grow in seasonally dry or cool environments. The species have adapted individually to these three habitats. Possessing neither Phalaenopsis nor rhizome, Phalaenopsis shows a monopodial growth habit: a single growing stem produces one or two alternate, thick, fleshy, elliptical leaves a year from the top while the older, basal leaves drop off at the same rate. If very healthy, a Phalaenopsis plant can have up to ten or more leaves. The inflorescence, either a raceme or panicle, appears from the stem between the leaves. They bloom in their full glory for several weeks. If kept in the home, the flowers may last two to three months.
Some Phalaenopsis species in Malaysia are known to use subtle weather cues to coordinate mass flowering.
