I tried a Thing this spring, whereby I attempted to grow another rose bush. I had a cutting from my lovely yellow rose bush, and I planted it in a potato and hoped for the best.
The cutting did not survive. I was a little bummed, but to be honest I didn't expect it to take. I didn't see a compelling reason to pull the dead stick, so I just left it there.
Fast-forward a few months, and I noticed that the spot where I'd planted the rose cutting had green coming up.
Rather by accident, I've got potatoes growing in a xeriscaped Las Vegas yard.
I doubt it will yield much, but hey! It's still fun! (And it does keep growing, so who knows what we'll get?)
