Background
Phalaenopsis amabilis (Phalaenopsis aphrodite Rchb. F.) is an orchid family Phalaenopsis, is native to subtropical rainforest region, and is an epiphytic orchid. The white and thick air root of the butterfly orchid is exposed around the leaves, and has the functions of absorbing nutrients in the air, growth and photosynthesis. In the new spring season, long pedicel of the butterfly orchid plant is extracted from axilla of leaves, and flowers shaped like butterflies are formed, so that the butterfly orchid plant is deeply favored by flower fans and is called as 'after the cattleya hybrida'. Distributed in thailand, philippines, malaysia, indonesia, and taiwan, china.
The butterfly orchid has a long flowering phase, generally 2-3 months; however, in order to make the growth conditions of the phalaenopsis harsher before and after the flowering phase, the risk of the flowers withering can be caused by taking little attention.
