We are Zone 5a in Canada, which is roughly Zone 4 USDA.
They aren’t all native, but we try to choose native plants when we buy new. We inherited many when we moved here.
We weed and I occasionally add fertilizer in the form of alfalfa meal. We haven’t quite figured out how to get our compost hot enough, but I hope to add some in the fall as well.
Fair, and my partner has probably eaten a little bit of each of the plants shown. These plants are not grown for our consumption.
The roses also generate rose hips but we leave those for the other residents.
