If its any help, they do not survive outside here in Sydney (min winter temp 41degF) and the plants do not have an annual cycle of growth and dormancy, rather the cycle is well over a year and so the plants are seldom in sync with the natural seasons (or with each other for that matter).
With numerous (but by no means all - a lot can be grown successfully) tropical plants outdoors in the Sydney climate, we find they survive winter and then expire in spring when conditions warm up. (Presumably when pathogen activity resumes but the plants are still suffering the after-effects of winter cold stress and have little resistance).
