I have my own garden, and with a very suitable climate to grow a large variety of things. The truth is I grow far too many things to name them all. Right now I am dealing with several fruit trees on my property. I have a heck of a lot of prune plums this year. I'm making apple/pear butter tomorrow. I already dehydrated over 20 lbs of plums into prunes. They're like candy, and keep very well for a long time.
My staples, aside from the fruit trees on my property, are potatoes, onions, garlic, beans, peas, cucumbers, carrots, kale, and squash, just to name a few, and I grow most of my own herbs as well. I also have a Bay Laurel bush. My kale often grows well into winter here. I also have a greenhouse that works through the winter months.
I love gardening, but I still consider myself somewhat of a novice. I am always learning, but I still make lots of mistakes. I tried growing melons this year, which was a complete fail. However, they do grow locally on some farms, so I wanted to try this year. I have bought local melons before here, and they're awesome. I've also had bad luck with corn. However, some of the tastiest corn I've ever eaten in my life grows just a few kilometers down the road.
I use many things daily or almost daily. Having your own herbs on hand is a wonderful staple. I will be planting next years garlic very soon. Garlic and onions are something I consider a huge staple. A lot of the fruit I either preserve or dehydrate. I picked a couple gallons of blackberries from my backyard this year too. I make pickles as well.
You can do herbs on an apartment balcony...tomatoes too. I have a friend that grows beautiful tomatoes on her balcony.
