I have had the Euchile citrina in my collection since I got it in bloom in 2004. I moved it from a pot to a mount. Since then I have tried it all over the growing spaces and it has never bloomed for me.
Euchile citrina grows in cerntral and southern Mexico with a strong lemon scent. It needs bright light and a dry winter rest. The genus Euchile contains 2 species from Mexico. They used to be Encyclia but were removed for technical reasons. Definitely need a dry winter rest.
This plant is a small backbulb division potted in sphagnum over peanuts in a 2-inch plastic pot. When I removed the plant from the mount there was a group of three pseudobulbs and these were put on the $5 table. There was this separate single very tiny backbulb. I was going to toss it, but couldn't. So I am putting it back in a pot and am going to give it one more try.
