it was one of those plants petco had in the tubes for supposed to be underwater but really does better out of water. cant remember what its called..
I believe this is dependent on species of sweet potato, I think some of the more decorative variates can be grown year round. I will have to look into it more, this is getting more into my wifes area lol.What happens though after they produce potatoes, does the plant die? Or would this be a continue produce producing plant year round?
