Me too.

One of our big unexpected scores was, about three years ago, a native black raspberry sprouted and started growing from under our covered front porch. My guess is that it was planted by a mouse or squirrel.

It doesn't root well from cuttings, but if a branch reaches the soil, it will burrow down and sprout, creating a new plant. Blackberries spread this way as well.

Anyway, this is on the northwest corner of the house, and shaded by the porch and a couple of big bushes, but it has still given us fruit every year.

I've now got half a dozen more plants that we've started from this one, ready to go into the ground, with which I want to create a living fence around our orchard.

Hopefully this will help to deter the deer from breaking the branches of our fruit trees. In any case, they should give us some yummy fruit, so it's all good.
