At the Shaker village in Canterbury, NH there was mulberry tree. It was pointed out to us by one of the workers. She encouraged us to pick some and eat them.
I will say that they were absolutely delicious, although a little messy. I had never seen a mulberry tree before and wonder if they don't grow in NY state. I think they definitely should! I would like one in my yard. I ate several of them before moving on to the rest of the museum.
I also wonder why in the nursery rhyme, it is called a mulberry bush. It was definitely a tree.
