Why do so many homes have a single seemingly random rhubarb plant in their yard?
I live in the PNW and it seems like every house I've lived in has a single rhubarb plant in the backyard. I've seen them in other people's houses too. No one seems to know how it got there, it survives anything, and it never seems to spread. Year after year it's right there like some kind of immortal ancient entity that was here long before me and will be here long after me. But I suspect there must have been a rhubarb craze and one time. I have never heard of that though.
