This plant is growing in a flower bed that I have at work. It is more like a small tree with thorns all the way up the trunk and out on the branches. As it has become colder, the leaves, then the branches are falling off. The leaves smell good when you break them in half. This plant does not secrete any milky substance like a thistle. I am uploading a picture of one of the branches that was left on the plant for better identification. Thanks for your help.
Thanks Chris. After doing some work researching this plant I am delighted to have it in my collection. I am learning the ways of the Native American and this plant is not only medicinal, but also a culinary spice. The bark and berries were used to numb toothaches (thus the nickname Toothache Tree). From what I have read so far, the outer shells of the berries are used by Asian cooks for a Sichuan Pepper.
