I've always wanted to start a garden but I'm not sure if I would be any good at it, mainly because things that require me to pay attention to them tend to die (goldfish, plants, girlfriends). Hell, I even killed a cactus one time.
I think Wilberforce should know what you can and can't plant though. I know Wilberforce isn't supposed to be the brightest bulb in the crate but this is stupid even for him. But what do I know? I thought that thing was a pickle and not a spade.
