There are many North American tree species we are continually collecting. Many of these species end up in our mixed species lines. We will however pursue and collect these materials upon request . Some of these species will require additional time to source and collect and may come from several locations. We enjoy the challenges of collecting and procuring these requests to offer unique options many companies do not. Our enjoyment comes with working one on one in order to produce these rare options in our boutique approach to problem solving. Rare and uncommon species we will source include, but are not limited to; Butternut or white walnut (Juglans alba), American Cherry (Prunus serotina), Locust (Robinia sp.), Black and White Ash (Fraxinus sp.), Elm (Ulmus Americana), and Sassafras (Sassafras sp.)
