In general, Hedychium bloom very late in the fall and so your climate is working against you in a big way. What many in the north try to do is get them in a warm place in April to try and get them growing inside and then put them out when the weather permits. By doing this you have extended your growing season by 2 months and you can get flowers late in the year. The main reason I grow Curcuma and Kaempferia and Globba.....they are winter dormant and flower every year for me without to much fuss. Best of luck :o) Dan
