Question about Cold hardiness of ornamental banana plants in zone 9.
 

Dear members,
New year I will be move from Thames which is in zone 10a, to Christchurch (New Zealand), which is in zone 9a, with average minimum air temperature -4 oC below freezing point, but it can go down to -6 oC few nights on July. Thames have 15 ground frosts per year. Christchurch have ground 80 frosts per year.

I had musa velutina, musa ornata, musa mannii, musa coccinea and musa violacea and hybrid musa mannii X musa aurantiaca had grew well and successfully survived the winters in Thames, for 18 past years.


Question:
Can musa mannii, musa siamensis, musa ornata, musa velutina, musa aurantiaca, musa coccinea and musa violacea survive growing outdoor in zone 9a all the whole year in Christchurch ???

Siamensis, ornata, and velutina survive in the ground in my zone 9a Gulf Coast Louisiana. Coccinea will come back for a few years but will decline and die eventually. I can't help with the others.
