salem salvia and summer squash


I was so excited to see some squash blossoms and tiny squash forming when I checked on the plants yesterday.  Yellow crookneck and zucchini squash have always done well in a certain place in our yard, which, by the way, we do nothing special to, so I planted 2 zucchini, 1 yellow squash, 1 cucumber, 1 pumpkin, 1 Jack-Be-Little, and 1 green winter squash.  As for the salvia, I love the color.  It does so well with so little attention.  What are your lowest maintenance plants - vegetables or flowers - that seem to flourish no matter what?
