Cold hardy tropical fruit trees for Zone 9

Q: Can you suggest tropical fruit that can be grown (cold hardy) in Zone 9?

A: There are quite a few tropical/subtropical trees that will grow well in zone 9. Our favorites are: Figs - very cold hardy and drought tolerant.
Loquats - grafted trees that start fruiting right away, reliable producers.
Tropical Mulberry - very fast growing trees that can take freeze, heavy producers.
Macadamia - these trees are of a compact nature, very easy to grow and start producing nuts right away.
Many different varieties of Eugenias - tropical cherries - all-time favorites. Another tropical cherry - Malpighia, or Barbados cherry - starts fruiting in small size under one food tall! Great for containers.
Tropical (Low Chill) Peaches, Nectarines, and Plums. See full list of low-chill, relatively cold hardy fruit trees.
And of course - Bananas!

Don't forget to fertilize your fruit trees to improve their cold hardiness!
