I have tried numerous times and numerous ways to get cuttings of our plant
to grow without success. Is there a secret I need to know?


Bottom heat and mist during summer (April to September) about 6" long, I
use 3 node cuttings with two leaves removed. It is possible to do hard
wood cuttings when they are dormant but its a bit heavy on the
propagating material especially in the uk where they don't make that much
heavy wood. Cultivars vary a good bit in how easy they are, I have a pink
that roots in about 10 days while a purple takes 3 months.
