Hi Jeff,
Most of the Magellanica and Triphylla types grow more than 3ft. in your climate.

This mail order company might be of use to you, see link below - Kath:)

Here is a link that might be useful: http://www.fuchsialand.com/

Kartuz (S.D. North County) has them listed. I've had a couple of plants labeled as F. boliviana that turned out to be something else, or were perhaps hybrids, so seed from verified F. boliviana might not be a bad idea. If you like boliviana, you'll probably like Fuchsia 'Fanfare'. It will get 8-10 ft, tall, the flowers are well-shaped and large and it is fully mite resistant. F. regia ssp. regia has flowers that are just typical but it will form a clambering liana up to fifteen or twenty feet with support (typically a tree). It is not self-supporting, but looks good draping over a fence or hanging down from the branches of a tree.

I have both the red and the cherry and white varieties. I can sell them or trade with you.
