Description & Notes:
Paraphalaenopsis labukensis is an extraordinary, pendulous orchid. It has extremely long, fleshy, cylindrical (terete) leaves that can reach an impressive length of over two meters in cultivation and resemble thin cords. The short inflorescence produces several waxy, strongly fragrant flowers (approx. 6 cm wide). The petals are characteristically twisted and display cinnamon-brown to brownish-yellow tones with a contrasting, lighter lip.
In cultivation, the species requires conditions similar to those for Phalaenopsis, but due to its strictly pendulous growth habit and enormous leaf length, it must be mounted or grown in hanging slatted baskets. It prefers bright to semi-shaded locations without direct midday sun, as well as consistently high humidity. The substrate or roots should be watered regularly, but must be able to dry quickly after watering to prevent root rot.
