Your article is what I have been waiting for. I live in Walnut Creek, CA with dry hot summer & somewhat mild frost free wet winters. Planting cool vegetables makes more sense to a lazy gardener like me. Letting mother nature do the watering when we do get rain. Growing up in an Asian family & being more a custom to sharper tasting vegetables, I am glad there are other choices. Farmer's market or chinatown is not far but home gown always taste better.
I hope this has encouraged you to grow some of your familiar childhood vegetables! The differences in the values of vegetables of other cultures fascinates me - tart, sweet, crunch, sharp, bitter , and the textures of leaves and stems...it makes a meal really enjoyable - beyond flavor - a whole experience. Most Americans don't eat food this way, and I think they are really missing something.
If you are having trouble keeping your garden watered in dryer times, think about unglazed Olas. You won't need to put water in them very often if you cap them off to prevent evaporation, and water goes directly to the plant roots. Great for the gardener who wants to reap the rewards without so much effort. Olas should be fairly easy for to you find in California, especially in Mexican Pottery outlets.
