I do not grow these plants myself, but from what I read in "How to Know and Grow Gesneriads", pearcea are very similar in growing requirements to Kohleria. On the Gesneriad Reference website there was a mention that the plant likes to have higher humidity and less light than kohleria. Maybe your problem is too much light? I am sorry that I could not be of more help, hopefully someone with more knowledge will pipe in.

It sounds like you're treating it about right. I don't have a lot of experience with Pearcea, although I did manage to bloom P. hypocyrtiflora several years ago. It bloomed during the winter in an unheated basement! The plants seem to like relatively low light (far less than most kohlerias), high humidity, and a well-drained medium that never dries out. This is one of the more difficult species to bloom; cool temperatures seem to help trigger blooming. It forms a large, sprawling, shallow-rooted plant that spreads by branching and by stringy rhizomes. No dormant period that I know of.

Bubba, I think you're in southern Virginia but it sounds like you might be interested in a couple of groups up our way. One is the local chapter of the Gesneriad Society, and the other is DCTropics, a local group of people growing hardy palms, (sub)tropicals & other rare and unusual plants. The two groups are very different, but there's some overlap between them. Send me an email if you want information on either group.

This is an old post, but I think I'll add to it anyway. I've been growing a P. hypocyrtiflora from a cutting acquired at least 6 months ago. It is potted, but I, too, chose to give it a terrarium (20-gal. aquarium) environment. Something like 2 months ago I noticed 2 buds starting to form, then they just sat there for the longest time. Finally, 3+ weeks ago, the buds began to grow larger & their pedicels grew longer. By 2 weeks ago, the blooms were peeking above the leaves, but continued to swell a little larger. Today, having decided the blooms must be sexually mature enough, I cut both opened and self-pollinated them.

I'm hopeful that I'll get viable seeds, however this plant is supposed to be easily propagated from both leaf and stem cuttings. The leaves can be cut into segments the way begonia leaves are often propagated and I think they can also be kept whole, with a piece of the petiole attached and rooted African violet style.

It is correct that P. hypocyrtiflora prefer high humidity and even dampness. They are a member of the Gesneriad plant family, which contributes many plants that are suitable for houseplant culture. There are over 3300 known species and countless hybrids.

The Gesneriad Society (originated as The American Gloxinia Society) is a great organization. Since joining, I've learned a great deal, attended a couple of the annual conventions and have acquired quite a large collection of plants. It is a great group to belong to and very welcoming of new members. There are also a number of satellite chapters.
