Welcome to the organization bjorkid!
I grow the Red Iholena in Zone 10 Florida. I have two Red Iholenas growing. I've had them in the ground for 1 year 5 months. They suffered 1 freeze in January 2008, Two in 2009, January and February. They do not like freezing temperatures but did survive all three freezes. But they did not do as well as most of the other cultivars under these conditions.
I have a picture of one in my photo album that was taken recently after the freezes.
Point is Protect them, they look good, but they do not take the cold well!!! Best wishes and good growing!!!
