I've been growing a garden every year for a few years now. Up until now I've stuck with the standards: carrots, tomatoes, beans, broccoli, peppers, onions, potatoes, etc. This year I wanted to try some perennial eddibles. Something unusual, maybe difficult. I've already had my strawberries for a year and a half, but that's a pretty normal plant. After careful runner control, this year the plants are quite large and healthy. I've enjoyed several berries and my kids even more than me.
This year I've planted four dwarf fruit trees. Dwarf types dont get very big. Like 10 feet tall max. I had a semi-dwarf apple tree when we moved in, but the fruit was sour and left a mess all over the yard. I pulled it out and now have pear, peach, red apple, and apricots. It will be a few years before I get any fruit, but when I do it will be awesome.
I plan to let the strawberries take up the whole front raised area. Maybe let the asparagus spread along the inner wall a bit. Dwarf tree in the corner. Artichokes or something else in the rest of the space. Melons or cucumbers could fit.
