The circled plant in the foreground is a green onion from a bunch I bought at the grocery store. I planted it because I couldn't eat all of them before they went bad. The rest of the first row is beans, with a few lentils planted at the end. Both beans and lentils came from grocery store packages.
In the back bed are a couple of tomato plants (bought; sorry), a small stand of lettuce and one lonely pepper plant. That's a volunteer amaranth circled - one my daughter planted a few years back called "Dragon's Tears." I suppose you could eat the seeds as well as the leaves on this variety, but I haven't tried it.
At the end, spilling onto the walkway, is a patch of purslane, which is a very good wild vegetable. There's some of it in the beans, too. I let it grow, they do well together.
You see clearly that my garden and yard are not the perfectly trimmed kind that looks like everyone else's. ;)
