The dwarf mulberry gets lots of berries on it every year.
I saw you question about overwintering on another thread. I overwinter my grafted shimps in my greenhouse(unheated) but my old business partner, who only has a small collection left, has found a great way to overwinter his small Ishi shimps in NE Ohio ( zone 5). He put a small shelf on his living room windowsill ( inside) and he sets them there in winter and pulls the drapes around them at night. They stay ( evidently) at a near perfect winter temp because his do better than mine that are greenhouse grown ( which gets pretty cold).
