I don't know about any nurseries with AeAe but when I was down that way I stopped in Carlsbad (which is on the way) at the Flower Fields
The Flower Fields. I don't think they are open now to the public, but I do know at the base of them was a very nice nursery where I got myself a nice 5ft dwarf brazillian for fifteen bucks (they were half off) but they had a nice selection inside of Bromlieads, they also had some nice Japanese Maples, and interesting grafted citrus trees. They are a bit expensive, but I thought it was a nice stop all in all.
