BK, someone shared several different gingers with me this past summer. I've only grown them one season. But, like Dr. Dawg, my most reliable is white butterfly ginger, hedychium coronarium (sp.?) I have a tall peach NOID hedychium which is also reliable for me. I've had both of those for a few years. What is the ginger in your photo? It looks like a spiral ginger, costus, but the flowers look huge, more like red ginger, alpinia purpurea. They are very large and healthy looking. What type of gingers do you grow? Xerantheum on this site, also grows several gingers.
