Phalaenopsis amabilis

Moth orchid

The white moth orchid is a lowland epiphyte found from the Philippines and western Malesia to New Guinea and north-eastern Queensland. It hangs from trunks and branches over rivers, streams and swamps in humid rainforest, usually below about 600 m. It wants steady warmth, shade, humid but moving air, and roots that dry quickly after each watering. It is a parent of most modern white Phalaenopsis hybrids.

Where it grows wild

An epiphyte on tree trunks and branches, often overhanging rivers, streams and swamps, in lowland rainforest with high humidity and free air movement; rarely on rocks. The leaves hang downwards, which sheds water from the crown, and the thick roots cling to bark in the open air.

Literature gives sea level to about 600 m. The measured records (18–780 m, median 165 m) agree, with a few slightly higher.
