Hello GingerSt
I'm not a specialist about gingers. But here is some information, as a starting point, about some more or less hardy gingers :
- Hedychium coccineum (red ginger lily) orange/red flowers
- Hedychium coronarium (Hardy Butterfly Ginger) white, z7+
- Hedychium densiflorum
- Hedychium ellipticum
- Hedychium flavescens
- Hedychium 'Gold Flame' peach/white, z7+
- Hedychium 'Dr.Moy', z7+
- Hedychium spicatum
I'm sure there are many others, but hope it helps.
Regards, Etto
