Banana plants [no idea of the species] seem to thrive here, to the point of being a nuisance, once established they're damn hard to get rid of, and they don't often produce worth-while fruit (may just be the variety?).
As well as the gardens I've got a lemon, kaffir lime, naval orange, satsuma mandarin, blackboy peach, yellow flesh nectarine, red plumb, peacharine, and guava (the small one, more for the birds than anything!) trees growing on the bank beside our driveway. They're only in their second summer now but hopefully we'll have plenty of fruit in the summers to come. I just need to get a rifle to keep the possums away!
