We planted an pomegranate tree in our front yard. It's a beautiful bush-like plant that is ornamental, and hopefully, delicious too. We have a few flowers that will hopefully turn into fruit. Native to Iran, the plant needs the right mix of temperature and direct sun.
Pink Lemonade blueberries are beautiful and tasty. This plant is much more attractive than the regular blueberry bushes that we have: lush, tall, and feathery. Plus tons of berries that get pink, instead of blue, when they are ripe.
A jack-o-lantern pumpkin gets off to a good start in our front yard. Italians eat squash blossoms in pasta, risotto, and stuffed with cheese as an appetizer. We love to dip them in beer batter and fry them up.
Tuscan Kale or 'Nero Toscana' that we planted from seed is doing well. I love this bumpy, blue variety and it works great in our kale chip recipe: http://www.frugal-mama.com/2009/11/mom-when-are-you-going-to-buy-some-more-kale/
