Additional Information: Laelia autumnalis is another popular Mexican Laelia that is frequently grown outdoors in Southern California. It prefers the same temperature range as Laelia anceps and Cymbidiums but readily adapts to greenhouse culture if it has cooler night temperatures. Does well mounted or in a pot with coarse growing media and excellent drainage. The plants require high light and cooler night temperatures (especially in the winter) in order to be successful in cultivation. Overwatering is the most common problem; reduce watering during the winter dormant period.
