Beautiful yard! I see I'm not the only one that squeezes as many plants as possible into my suburban yard...although yours looks like a half acre at least, while mine is a puny quarter acre.
I am lucky to be able to grow most tropicals down here, but envy those who can produce many of the fruits commonly found at the grocery store. Being in zone 8, I'm wondering why you haven't tried growing fruits like apples, cherries, olives, persimmons, pears, plums, apricots, figs, nut trees, pomegranates, etc etc? Don't get me wrong, I love what you've done with your yard, but think it may be difficult to sustain in the long run. I've had to learn some lessons the hard way..
I had several citrus trees at one point, but am left with two because they are tough to grow down here(diseases and insects are the main problem). As they've become infected with deadly diseases, I've had to cut them down. It was decided that there is no point in replacing them with another citrus tree if eventually, they could get sick and die. After years of caring for a tree, it hurts to have to cut it down.
Luckily, this turned me on to several EXCELLENT tropicals I previously had not even heard of.. Atemoya, Jaboticaba, and Sapodilla(my absolute favorite!...tastes like a fine pear soaked in brown sugar).
Anyways, lovely yard again and good luck with everything!
