It's worth knowing which weeds and decorative plants are edible in your part of the country. In southern California I often breakfasted on eugenia berries, included dandelion leaves in a salad, or roasted their roots for dandelion coffee, or snacked on natal plums or the rather bland fruit of the strawberry tree. Wild blackberry is a treat not to be missed in the northwest. In the Spring if you can run, just after Easter abandoned rabbits are fairly easy to wear out, capture, and dress for dinner. If you know your wild foods, life can go a little easier.
Be ready to be told that the berries you are eating are poisonous. If you know better, just ignore foolish advisors. I've been told eugenia berries are poisonous more times than I can remember, though I've been eating them since early childhood and every book on botany and horticulture notes that they are edible. On more than one occasion I've been told that a perfectly ordinary fig or strawberry was poisonous. Just figure that the foolishness factor on unsolicited advice is about 90%.
