Santa Rosa plums, or Prunus salicina, is a fast-growing fruit tree that produces delicious and juicy fruit during the middle of summer. They were developed by Luther Burbank in 1906 in Santa Rosa, California. He began to import Japanese plums in the early 20th century, and he eventually created the Santa Rosa plum tree. It is a cross between Asian and European varieties of plums.
The Santa Rosa plum tree has green leaves, and the small fruits grow in bunches on the tree. The fruit has deep red chalky skin with yellow and orange flesh. Occasionally, the skin has a purplish color, and the flesh is red. In the blooming season, which is during July, small white and pink blossoms will begin to grow on the trees. Fruit can begin to bear during the first year of its growth. When the tree is fully mature, the Santa Rosa plum tree can grow up to 25 feet tall and 10 to 20 feet wide.
The Santa Rosa plum tree is best suited for USDA regions 5 through 9, and it thrives in regions that are warm and dry. In addition, it is drought tolerant once it has been established.
