The genus Phalaenopsis comprises about 50 species and over 32,000 registered hybrids which produce oval, fleshy, sometimes mottled, green leaves. Their flowers remain in bloom for a long while. Moth orchids are one of the easiest orchids to grow in the home. With a few basic requirements, these plants will reward owners with several months of beautiful blooms. It's recommended that, when the blooms are finished, the spike is cut down to the level of the leaves – that way, the plant will bloom with larger flowers, and produce a strong stem within a year. Unlike many other orchids, Phalaenopsis can be repotted at anytime, but it is usually best to do so when not in bloom.
