The only thing neither location really controls is >sunlight (intensity, duration, angle, etc.). Lee, Apparently plants in the wild side-by-side can flower at totally different times of year. I was reading about them a few years ago and there seems to be no distinct reason why they flower or produce leaves.... they just do it at whatever time suits them. Each leaf can live for about 18 months, followed by a couple of months dormancy and then either another leaf or a flower. It doesn't seem to be anything to do with climate, in that the time of year is irrelevant and the plant just does it's own thing whenver it feels like it. They are absolutely fascinating plants!!
