Moorpark A distinction should be made between the old English variety known as Moorpark and the Wenatchee Moorpark developed in Washington and now making up much of the Washington tonnage. The Moorpark as grown in California has fine quality with a rich plum-like taste. However, it ripens unevenly. The fruit matures and is marketed in California later than Royal and Tilton. The Wenatchee Moorpark is similar. Origin is not definitely known but is considered to be about 1880 in Washington or California. It has orange flesh and skin, unequal halves, large size, uneven ripening, fair texture and quality, may be used for fresh market or processing.
