This is a wild species that has not adapted to a temperate climate and its winters. It is used to growing 52 weeks of the year and if you cannot bring it indoors over a cold winter to continue growing there, then it is pointless trying to treat it like a cultivar and try to make it as dormant as possible, as it will not survive such treatment.
