Thanks Jean,
I especially like the aggie-horticulture link. Useful info with photos. A lot of things shown in the link would need to be grown in a container here. My location just gets too cold in the winter. I'm going to have a porch and garage filled to overflowing this winter.
Yours are beautiful. I'm satisfied the plant I saw was in the genus Hedychium. I'm not as confidant about specifics beyond that, though. That's a lot. Here's another monstrous bloom I saw in Costa Rica that I have tagged as 'probably a ginger'. It was more what I associated with ginger blooms, so I didn't connect the two as both being gingers. Are you any growing with blooms sort of like this?
