sbailey, I didn't buy the plant- it was a gift, and I don't know where my friend got it.
The only source for it that I know of is Plant Delights, a nursery in Raleigh, NC:
As zuzu points out, it may also be available as 'Angel Earrings Cascading'. It seems to be distributed as a Proven Winners plant, so if there's a good nursery near you that sells Proven Winners, they might be able to order it for you?
Also, there are other heat-tolerant fuchsias in the Angel Earrings series.
It is heat-tolerant and hardy here (I'm on the cusp of 8b/9a). I've had it several years, and I do bring it inside if a freeze is forecasted because it did take a while for it to grow back after being winter-killed.
I hope this helps,
