Abstract
A new and distinct variety of plum tree that is characterized by producing a semi freestone fruit with good dark red coloration and is ripe for commercial harvesting and shipment June 3-June 14 in the San Joaquin Valley of Central California. The new variety is closely similar to ‘Santa Rosa’ plum (non patented) from which it is hybridized but it is distinguishable in that it ripens seven to ten days before ‘Santa Rosa’ variety. The fruit of this new variety is medium size with good flavor and good dark red color which makes it greatly acceptable for the consumer.
