Moth Orchid (Phalaenopsis amabilis) — identification, habitat & look-alikes

Moth orchid is a tropical orchid that grows on trees and carries several large white flowers on arching stems. It is one of the wild species used to breed white moth orchids sold in U.S. flower shops, but a store-bought plant may be a hybrid rather than this species.

Appearance

Leaves: Broad, thick, glossy green leaves grow close to the base.
Flowers: Arching stems carry large white flowers, about 3–4 in (7–10 cm) across, with yellow and reddish markings near the center.

Look-alikes

Both have large white flowers, so an ordinary photo may not settle the species. A close-up of the flower center can show two small teeth on the raised part in this species and four in the lookalike.

Why they get mixed upThe two have been confused in horticulture for a long time.

Where it lives

Typical habitats: Indoor collections
Greenhouses
Range: It grows wild from Indonesia and the Philippines to New Guinea and northeastern Australia. In the United States, it is grown as an ornamental orchid.
Preferred conditions: It is an from humid tropical forests, growing attached to trees rather than rooted in garden soil.

Growing it

Care: Many familiar white moth orchids are hybrids with this species in their ancestry.

Name and classification

About the name: “Moth orchid” can mean the genus Phalaenopsis and its many hybrids, not just P. amabilis.
Varieties and forms: A large white flower on a cultivated plant does not by itself prove that it is this wild species; many shop plants are hybrids.
