I've had these Titanopsis calcarea for a year and they seem to like it a lot here. If you take these two plants together, they've developed seven new branches out of three they had last year which is a great accomplishment. After all, the more growing points there are, the more chances for flowers. Now it's getting tight for them and I'm thinking of setting them apart at last. I can only offer 5x5cm pots but at least they won't have to share one.
