Phalaenopsis amabilis
Moth orchid (Phalaenopsis amabilis) is an epiphytic orchid from rainforest that grows on tree bark and is widely grown as a houseplant. Success depends mainly on bright indirect light, warm steady temperatures and careful watering and feeding.
Phalaenopsis amabilis, commonly known as moon orchid, moth orchid, or mariposa orchid, is a species of flowering plant in the orchid family Orchidaceae. It is widely cultivated as a decorative houseplant. It is an epiphytic or lithophytic herb with long, thick roots, between two and eight thick, fleshy leaves with their bases hiding the stem and nearly flat, white, long-lasting flowers on a branching flowering stem with up to ten flowers on each branch.
Phalaenopsis amabilis is native to Maritime Southeast Asia, New Guinea, and Australia. It has three subspecies: P. a. amabilis, native to the Philippines (Palawan), Malaysia (Borneo), Indonesia (Borneo, Sumatra, and Java); P. a. moluccana, native to the Maluku Islands (Seram and Buru Islands) and Sulawesi of Indonesia; and P. a. rosenstromii, native to Papua New Guinea and Australia (northeastern Queensland).
Phalaenopsis amabilis is reported to be very easy to grow as a houseplant, as long as attention is paid to a correct feeding and watering regimen. It thrives in a domestic temperature range of 17–22 °C (63–72 °F), in bright indirect light such as that offered by an east- or west-facing window. Specialist orchid compost and feed is widely available. Species and cultivars in the genus Phalaenopsis are recommended for beginners.
In cultivation in the United Kingdom, Phalaenopsis amabilis has gained the Royal Horticultural Society's Award of Garden Merit.
Phalaenopsis amabilis usually grows on trees, rarely on rocks, in rainforest where the humidity is high but there is free air movement. Subspecies amabilis has the widest distribution and occurs from Palawan in the southern Philippines to Borneo, Sumatra and Java. Subspecies moluccana is separated from subspecies amabilis by the Wallace Line and is found in Sulawesi as well as Seram and Buru in the Moluccas. Subspecies rosenstromii is native to New Guinea and Australia where it occurs on the Cape York Peninsula between the Iron Range and the Paluma Range National Park. It is separated from subspecies moluccana by Lydekker's Line.
