Cultivation:

Laelia tenebrosa is a vigorous, easy-to-grow plant and one that most beginning orchid hobbyists should be able to grow well. It needs the same growing conditions as most cattleyas, including a day temperature of 85 F (29 C), night temperature of 60 F (16 C) and lots of moving air. Like Cattleya warneri, its Brazilian neighbor, it benefits from slightly less sun than the sun-loving cattleyas of Colombia, such as Cattleya warscewiczii, but will still grow fairly well even in high light levels.

When actively growing, it requires more frequent watering and should not be allowed to become completely dry. It should be kept on the dry side after flowering until it begins its new growth..
