Had a very old plant of this years ago, a division from a friend's plant which I'm fairly certain was a division of a wild-collected plant from the 1960's or so. It was a sickly thing, only bloomed a couple times over the 15-20 years I had it, always trying to die. It finally succeeded and I got another a few years back of seedling origin, which has done well for me and become quite a robust grower and bloomer. Gave me three flowers two years ago, took a rest last year and had only one, then this year, back to full steam with three again. Hard not to like this one!
