For those who grow petrocosmeas -- do you have any special tips on their care? I have two small plants of P. forrestii, and I just put two leaves down of P. rosettifolia. Say, compared to african violet care, what do these guys like different?
I read that they prefer cooler temperatures -- so how cool is cool enough for them to like? I have a drafty windowsill where themperatures drop to 50F in the winter, and, well, it's quite drafty. I mistakenly put a couple of african violet babies there last winter, they never quite recovered. Would the petrocosmeas like that spot, or they are better off in a kind of spot that violets like?
Do they mind summer temperatures of up to 80-83F?
Also, do they need something beyond basic care in order to grow into these perfect symmetrical rosettes I see in online photographs? Or they will naturally grow perfect like that as long as they are healthy?
Also, propagation -- I put down a leaf of my p. forrestii, just to see how easy it will root, and then I pulled it out a week later, and it already had a bunch of roots. Will p. rosettifolia be just as easy to root? (I won't be pulling those out to check, since I only got those two leaves, so I'm curious :) ). And will they send plantlets just as easily, or they'll sit there forever with just roots?
