Re: Question about Cold hardiness of ornamental banana plants in zone 9.
Im a 9a grower, but we dont have anywhere near 80 frosts a year.. we probably have 15 or less on average. I have namwah, cavendish, blue java, raja puri, pisang keling, pisang klotek, viente cohol, and dwarf red all in the ground outside. I have the pstems covered with plastic, and that appears to be sufficient. Many of the leaves are burned or partially browned for the 3 or so frosts we've had so far. In my area, it appears protecting the pstem is all that is really needed to keep in the ground. Hope that helps
