Prosthechea cochleata or Cockleshell Orchid is a black orchid. Or at least in part: the labellum, which is placed over the flower and forms a hood, is dark purple, almost black.
This orchid is grown for its original and long blooming flower that lasts up to 6 months.
It is the national flower of Belize.
Each oblong pseudo-bulb bears one or two linear non-succulent leaves.
The flowers are unusual because the lip is generally below the column in orchids while among members Prosthechea, the lip forms a hood above the column. Hence, the flower is upside down. While the Prosthechea usually have 1 anther, Prosthechea cochleata is a self-pollinating variety with three anthers.
The flowers appear on an apical and erected flower stem, measuring up to 40 cm, where the flowers appear and bloom successively.
Flowering can last six months, starting in the spring.
