This plant grows in some ornamental gardens here in Ontario, Canada, USDA hardiness zone 4. It is somewhere around 8 feet tall I would guess, and the leaves are huge. Looks too exotic to be hardy here but I'm presuming it must survive the winter or else they dig it up and winter it indoors (which would be quite a task). I've seen it in the same spot several years in a row, though. I've never seen flowers on it, so if it flowers in this climate it is at a different time of year. Thanks for any ideas.
