Currently, I have a basil plant in a pot on the patio, and there’s an oregano plant in my backyard that I planted many years ago. In California’s mild climate it survived the winter and grew into what could almost be described as a big oregano bush. My neighbors have an orange tree in their backyard; if an orange falls off the tree and lands on my side of the fence I might consume it.
In the past I’ve grown tomatoes, bell peppers, Fresno chilies, cucumbers, lettuce, Italian parsley, and cilantro, some with better luck than others.
In the wild I might occasionally stop and graze on blackberries along the local bike paths.
