Mine are actually not tropical but rather warm temperate. Some of them (including A. candidissimum) can be grown in your area. I bring most of mine in for the winter in my zone 3 garden, though. The approximate hardiness zones (according to Plant Delights Nursery) for these species are:
A. sikokianum - zone 4
A. kiushianum - zone 7
A. thunbergii ssp. urashima - zone 5
A. candidissimum - zone 5
I have overwintered A. sikokianum outdoors here before.
I have some A. triphyllum too, but I couldn't find the pics! I have some pics of my A. ringens around here somewhere too...
