Oh, also be sure to include some herbs! Chives overwinter well, oregano is perennial and easy to grow, lavender smells wonderful. Sage is my son's favorite; he pulls the leaves off and eats them plain. Basil is good as an annual, but won't tolerate any frost. Be careful with mint. . .it spreads like crazy and tries to rule the world. LOL It is good in a separate container, though.
