>>1105482Pretty much any nightshade/solanaceae family plant,
Potatoes: Peruvian cultivars are pretty neat. (pic)
Tomatillos: great for salsas and general Mexican cuisine.
Peppers: obvious
Black Nightshade (Eastern Black Nightshade or Garden Huckleberry): Similar to blueberries-blackberries in flavor, best in very light muffins and cookies.
Mints are usually super easy to grow. I use them for making candy, icing/glaze, some baking, and herbals/teas:
Peppermint
Spearmint
Mountain Mint
Lemon Mint
Catnip
Fruit trees/bushes/canes (always plant several of the same and mixed varieties for best pollination of most fruit trees):
Whatever is best for your climate and weather. If it snows in your area then apples, hardy peaches, and pears should do well. There's 100s of varieties. If you use pots, you can grow tropicals that you can put outside in summer. Those can be trees or stuff like banana plants and pineapple plants. There's stuff like golden raspberries, gooseberry, lingonberry, currents, seaberry, mulberry, elderberry, saskatoon, strawberry tree, etc. Most everything is plant and forget, but can always use some pruning for best results. Digging the $100 for trees and shrubs is also extremely important. Also, via cuttings, from your own plants, you can expand exponentially.
