Catasetum sp.

USDA Plant Hardiness Zone Map

Close

Catasetum have thick, cigar-shaped pseudobulbs which are clustered.

The inflorescence is borne on the basis. It consists of very fleshy flowers that are unisexual, which is exceptional for orchids. The colorful male and yellowish-green female flowers are typically situated on different plants. Which type of flower a plant produces is determined by the conditions under which it grows. There are rare cases in which a single plant in intermediate conditions will produce both male and female flowers. These flowers are markedly different in size and color. At first, taxonomists even thought they were dealing with different species.

Catasetum Orchidglade 'David Ranches' is a hybrid of Catasetum pileatum and Catasetum expansum.
