Very surprisingly, most people fail to realize that if a plant is hardy to a given climatic zone lower temperatures this single fact has nothing to do with the rest of its cycle. What is the use of having a plant survive the winter if it will never grow well or even flower?. Of course, some nursery people is very active in informing potential customers of hardiness of their plants but astutely add nothing of the rest. Hedychium gardnerianum, mentioned here is rather well known in downtown Buenos Aires and the northern coastal suburbs. That is to say zone 10 in winter and 10-11 in summer. It behaves as a perennial foliage plant (year round) grows quite neglected even quite dry in the worst heat of summer and flowers abundantly every year and it does very well in dappled shade. From the rhizomes there is a constant although not rampant increase. The dark green foliage is sumptuous and the yellow flowers with very long crimson anthers are stunning. Although there are other Hedychiums reported to be hardy, a climate in which they would not retain their perennial foliage and flower regularly is clearly not for such (and scores of other plants) although this spoils a good sale. This same plant brought some distance into the open land, with a say zone 9 winter has the perennial foliage battered by low temperatures and remains stunted.
