    Alright, who here has figured out the trick to blooming this species? I have mine in my cool case, as close to the lights as I can get it. It's grown very well for me this way and has become a pretty large specimen, but it doesn't flower. Anyone have any tips?

    Have you tried letting them go dry for longer in the winter?

    I've also seen clones that are sort of reluctant to bloom.

    It’s flowered once! I’m going to try giving it more distinctly wet/dry seasons. I might remount it with a bit more moss so it stays a bit wetter in the summer too.

    I grow (and bloom) mine with little or no moisture retentive material on the mount. In the winter I mist 2 to 3 times per week. I am growing in about 80% humidity. They are dry within a few hours of misting and then dry until the next misting. If I see the leaves start to shrivel a bit in the winter I add a watering now and then and increase the frequency of misting. In summer they are watered every day.

    Thanks Marni! What's your temperature range like for these?

    56F minimum winter nights, about 80F maximum during the day. I have grown them with 50F minimum nights, but I think they do better a bit warmer. I was looking at mine the other day and I do have some coconut fiber at the base of the plant on some of mine that are mounted.

    Every year I learn the hard way that you don't want to get the flowers wet. They don't last very long if you do.

    So I’ve tried everything with jongheanna with no luck for the last 5 years!

    I had a compot from a friend and the plants I kept for myself bloomed the very same year after mounting and then never again! I now have them hanging in the sunniest spot in the greenhouse and no shade cloth at all. I also do the drier winter routine where they see low-mid 50’s at night. Growth looks good (light green with slight anthocyanin tint in the leaves).

    So maybe I throw out the books...put them back in a shadier, uniformly-moist area...giving them the same conditions as when they were in compot? Or maybe I just start calling them Laelia again?

    I'm sure mine would do better if a little more protected from winter chill. (Probably would get bigger flowers/more of them) I wouldn't say that I grow them particularly well. But they're pretty reliable... hang out on the patio, get winter nights into the low 40's F and occasionally cooler. Winter days rarely colder than 60 deg F,usually more like high 60's. Summer highs from mid 80's F into the 90's, summer lows typically from mid 60's F to occasionally low 70's in August. Filtered sun. Basket with large bark seems to work best. I have one mounted and it's aggressively growing on the mount but I suspect that eventually it's going to be dropped into a basket. There seems to be a tendency, when mounted, to change direction and start growing off the mount, hence the basket. (I think of it as a 3-dimensional mount) Buds are big and fat... figure a week or two to bloom. So maybe just move to coastal southern California? ;)

    Yeah...I thought of moving out there once or twice. Andy offered me a job once...but there is the whole thing about affordability of real estate .
