I'm not a botanist, but I believe this beautiful flower is solanaceae, more commonly known as nightshade. Daum did not depict this flower very often, but it always made for splendid decoration. This example is especially fine with gilded details and a beautiful background that shades to yellow with green mottles at the bottom. The shape is very desirable, a flattened pitcher with an applied handle. Nice cabinet size at 5" tall. Gilded signature underneath, "Daum Nancy", together with the Cross of Lorraine.
