Yuko has mentioned the sweet potato plant in comics past - we left for one weekend and we came back it had exploded! Yuko was very pleased. I'm waiting for it to outgrow its pot and choke us in our sleep. You'll see. 

Did you know morning glories are related to sweet potatoes? They are. Yuko gave this sweet potato a home in our living room, and it's doing quite well. 

I don't think I actually knew what sweet potatoes even were until a few years ago - to this day my stomach turns at the horror of knowing what I missed out on. 

Books are still up for sale! I added a handy sidebar link (finally).
