Does zucchini grow well? It is probably my favorite vegetable, both flower and fruit. We grew peas a few years ago, but keeping them neat is a pain. Are beans like that?
Zucchini is almost impossible to kill here. You should definitely try it. A good friend is currently being overwhelmed by them to such an extent that she picks half just for the flowers. Artichokes are nice too.
Put a tomatillo plant in. They grow very well and the green sauces and salsas made from them are easy. A cherry bomb hot pepper is also a great plant, hollow the red golf balls out, stuff with goat or feta chesese spiked with olives and lemon peel and pick them up on the grill to make a great summer side with anything grilled.
there's a good book called "square foot gardening" that is pretty much the american version of french intensive.
We use this book with success and have three 4' x 6' raised beds. We stagger plantings of beans, peas, lettuces and chard so you can have different crops throughout the season. We grow chard and kale over the winter too. We use a single square of about 5' x 5' for four zucchini plants. Herbs are in a set of pots as are cherry tomatoes. I planted a rosemary hedge along the drive about ten years ago and it is an absolute beast but is a handy source of grilling skewers.
