I am not a fan of Immortality. It is boring with a "Historic" bent. There are better more modern types that will do well in your neck of the woods.
I like:
Twiggy
Zee
911 Remembered
Autumn Circus
Again & Again
Over & Over
Colortart
I have 30 more "RE" types, but they are recent additions and have yet to rebloom for me. Then again, I have not "tended" to them to enhance their chances of rebloom. I have changed that factor this season and hope to have a large rebloom season.
