Z.S. & C Company was founded in Bavaria in the 1880's. (Zeh, Scherzer & Co.) Maker's mark appears in green on the back of plate. Delicate gold trims the edge. The floral pattern is predominately lavender, red, blue, gold and green with black accents. I believe it matches pattern #9789. Measures 8.5" diam. Look for other Bavarian treasures in my booth.
