General Description

One of the most delicately beautiful of all the corsage orchid species, Cattleya trianaei is admired for its fragrant, ruffled, pastel winter flowers. An epiphytic (growing on another plant) tender perennial orchid from Colombia, it will form a lush, dense cluster upon a tree branch, wood basket or heavy pot in frost-free gardens. This species has produced many clones that orchidists have extensively used for breeding to create some of the finest hybrids (grexes) of corsage orchids known today.

Only one long, stiff, leathery green leaf grows from each club-like pseudobulb. It typically grows in two spurts in spring and in summer followed by a short dormancy in autumn. In the short but warming days of late winter into early spring, a pseudobulb will form two to three of its fragrant flowers on fleshy stalks. Each blossom is ruffled with varying shades of pastel pink and rose with purplish hints and a pink and magenta central lip. The specialized flower is pollinated by a certain-sized bee that can enter the lip and exit the flower.

Grow Cattleya trianaei in partial sun to very bright partial shade. No soil can be used; rather the plant can be supported in a coarse bark or charcoal media that allows water to freely drain. High humidity, excellent air circulation, and frequent rainfall in the warmth of spring through fall is ideal. Allow the plant to be slightly drier and receive more light in autumn and winter. Leaves can scorch in hot afternoon sun, especially with low ambient humidity. Leaves also become overly yellow-green when light is too intense. Lack of sunlight also can prevent flowering.

Use the cut flowers for leis, hair decals, table garnishes or floral arrangements. Consider repotting this orchid only if it is greatly rootbound, and then only after it finishes flowering and new roots are beginning to elongate.
