Flower Description:

Bloom Season:

Growing Temperature: Intermediate to Warm. In its native environment, summer days average 82-84 F (28-29 C), and nights average 71-72 F (22 C), with a diurnal range of 11-12 F (6-7 C). Winter days in its habitat average 77-79 F (25-26 C), and nights average 64-65 F (17-19 C), with a diurnal range of 9-11 F (5-6 C).

Growing Information:

Light: Standard Cattleya conditions.

Humidity: Provide 80-85 percent humidity for most of the year. Its acceptable for summer humidity to drop into the 75-80 percent range.

Water: Plants should be watered regularly throughout the year, but they must dry rapidly after watering. Make sure that the plants never stay dry for long periods of time, however. Give mounted plants a daily misting in summer with a thorough soaking of the entire plant and slab twice a week in summer, or three times a week in extremely hot weather (adjust for your climate). Water should be reduced somewhat in winter, but plants should never stay dry for long periods.

Growing Media: Plants are frequently grown mounted on cork slabs or in baskets, but some growers report success using pots with extremely open fast draining medium such as coarse bark nuggets. Whatever the choice of medium, it is critically important that the roots dry rapidly after watering or root rot is a near certainty. Use very small slabs for mounting this species because larger slabs retain to much water. Tree-fern slabs hold more water and should only be used only in very dry growing conditions. When mounting, do not use sphagnum moss between the mount and the plant because it retains too much moisture and promotes rot. Divide, repot, or remount only when new root growth is just starting. This lets the plant become established in the shortest possible time with the greatest success.
