Yes they are EXTREMELY hard to grow. I’ve murdered many to boot. Or they commit suicide (even ‘overnight’ on healthy plants).Nice to see your plants, Leslie.Important to say that violacea is not an easy species.Roots are easy to rot, it is because in its original habitat roots are growing free on air just on the surface of the trees and dry very quickly.In the other hand violacea love high humidity, cca 75-85% all in the year.
That’s why this is the only method that works for me.
