Petrocosmea

I do indeed grow them. You are lucky they survived as they are not really hardy. Keep them in relatively shallow pots (they are not frost hardy) in a frost-free greenhouse with good summer shading. They benefit from relatively high humidity. You can propagate them from leaf cuttings. Yes they flower in the autumn. They will benefit from some extra light in the winter.

The last question: Need Petrocosmea a dry season?
