I took a walk last night at the Gilcrease Museum and I am glad I did. I have tried to plant native species of edible plants and trees at my own home and have a couple of paw paw trees. They do not grow like a weed... they have been in the ground for several years now and have grown very little and have never, to my knowledge, produced a flower. Gilcrease Museum has a wonderful Native American and pioneer garden hidden at the end of a nature trail through the woods and past the ponds. They have planted and labeled many native species that were used by early settlers and Native Americans. Anyways I noticed some interesting deep violet/maroon flowers hanging from a tree and took a closer look. They had a VERY UNUSUAL scent. Almost like a vegetable smell. Anyways they were beautiful and were reminiscent of flowers in the night shade family.
