    I received this plant as a mature division about five years ago, and it has grown every year for me, but never gets any taller. The tallest growth, with leaf extended is ~4.5" tall. Five years and still the same. Healthy plant overall, but I hear that others have plants up to 18" tall?? 20 older now-leafless pbs, and 9 younger ones with leaves. It's in a 3" clay pot in fine bark, and seems to be healthy. I so want to see those beautiful red/pink flowers.

    What's going on?

    My guess is that you are growing it too bright and to dry. I've found they do best in intermediate conditions. I grow it in a fine bark mix so that it might be approaching dryness between watering but is never completely dry. I've grown it well in warm temperatures but it didn't bloom. Normally the pseudobulbs are proportionally much longer than yours.

    Since my growing conditions are probably similar to yours, I'll share my culture.
    I grow this species in a 3" clay pot in pure sphagnum. Less than Cattleya light, close to the north-facing window where temperatures are intermediate-cool during winter and intermediate-warm during summer. The plant is never fully dry. Humidity varies from 30% to 95%. I bloomed it for the first time last year.

    Thanks, both of you. It probably should be moister than I have been keeping it and in less light as well. As it has several new growths starting right now, this will be an excellent time to make and be able to monitor changes in culture.
