11h30 drive down the road, you'll be in Florida :) or you can shop online - EncantoFarms Nursery for instance .
Or you can try at your local nurseries in May - here at least, it is when they get their new batches of trees - and sometimes you can find a funny labeled tree - This year, I had my hands upon a "Green Jerusalem" figtree.
Sometimes you can be lucky.
This year I almost had my hands on a Brunswick - but it was in August, and the little tree had suffered from being in a 1 liter pot too long - The leaves were not good looking / FMV look iwhc could be due to poor watering, but ... No Risk !.
My plan is to go back this year to that nursery to check what they have.
And hopefully not to buy the tree, because for now I have to already let mine show what they can do - but in two years, if one of mine calls for replacement ...
For the trip, I know someone that sometimes goes to the Mediterranean coast - 10 hours trip for us as well - and I already began speaking to him about a visit he might have to do for me at some local nurseries :) .
