At our last meeting, someone asked about a
Kohleria hybrid that was not growing true from rhizome. Guess what? The latest issue of
Gleanings might contain the answer. Check it out: it's an excellent read. It's monthly, it's free, it's got pictures, and sage advice. Published by The Gesneriad Society (that's our parent organization, the international society), you can find it
here (and while you're there, you might want to subscribe via email).
