The rare of the rare. This amazing plant likes full to half sun with a fertile but well draining soil. If in a pot, let the potting compost completely dry before re watering as it has a habit of rotting otherwise. Hardy down to 10C, new growing buds will die in anything under 7C and if kept dry can most likely go down to 0C and the vine will go dormant but its not really worth the risk. They grow enormous easily can reach 15ft in two growing seasons from a cutting. For flowering you firstly need a old plant 5 years + as well as a large plant, as flowers on old growth.
