Cyrtochilum serratum is an epiphytic orchid from the genus Cyrtochilum.


Plants bloom during the winter with several 7.5 cm wide flowers.


Plants are found growing in the cloud forest of western Ecuador at elevations of 1300 to 3100 meters


Grow in cool to intermediate conditions with moderate light. Water the plant right before the potting mix starts to dry. Plants should be potted in a well drain medium such as medium fir bark.

This orchid is more sensitive to excessive heat than Cymbidium. Even with 50% shade cloth and daily watering, it will turn yellow and die if exposed to 90F afternoon temps. I was delighted to see it bloom in the cloud forest (cool and moist) in Ecuador, and had to have it. Bought healthy young plants from Ecuagenera, which grew well until hot summer temps fried them. Bought new plants, which are doing well in winter greenhouse, but will bring them into air conditioned room with fogger mid-June till mid-Sept.


Common name: The Saw Edged-Flower Cyrtochilum
