I really interested to hear if anyone in the North grows these and actually gets them to flower. You South-type people can comment too.
Got my first one Hedychium coronarium last year. It grew, but never bloomed. We had a really cold summer so that might be part of the problem. I've added a few others this year:
H. coronarium 'Luna Moth'
H. gardnerianum
Zingiber zerumbet
How should I be treating these?
