So, I thought I would share what I am doing. My space is about 20x25 in LA.
We started this last August 2011.
The ground gets at most 4 hours of direct light on about half of the space (a different half in summer and winter) -- the rest is dappled shade throughout the day-- from the Sapote tree -- or shaded completely from buildings
Growing here is;
40' White Sapote (it is really sick), Bamboo, Green Fig, Saw Palmeto
Nisturtium, Daikon, Radish, Water Hyacinth, Water Lettuce (plus a goldfish), Comfrey (true and hybrid), Cellery, Basil, Poppies, Marigolds, Tomatoes, Thai Eggplant, Japanese Eggplant, Rust Fennel, Broccoli, Sunflowers, Hollyhocks, Carrots, Lettuces, Rocket, Clover, Chili Mint (an asian mint don't know name), Mint, Beets, Kale Jackfruit, Chives, Lemongrass, Lavender, Roses, Peas, Bannana, Pennywort, Morning Glory.
Most I have seeded or plugged in the ground
And probably some stuff I forgot.
I scavenge broken tv's and use the mirrors to collect sun off of the fence to redirect it.
It's fun, but I really want more space! Gotta start somewhere however.
