I see, thanks to you both. I knew it was risky on the coast but from what I had been hearing about it I decided it was worth a trial. When I heard the words "long hot growing season" for some reason I thought that only applied to the ripening of the fruit, and the tree itself would rocket in most climates. Something I didn't take into account is how satisfying it is to watch a tree grow quickly.
This is a good thing though, now I know the importance of selecting the tree and not just the fruit. If you have multiple acres to just throw whatever in, go with the B. Madeiras and Ischias of the world. If you have a joke of a lot in coastal Del Mar (like someone here) plant producers.
It's also good because now I get to pick something new for that space... Purple Smyrna, LSU Purple... so many choices.
