Ruby Sweet Plum Tree
Description
Developed by USDA in Georgia, the Ruby Sweet Plum tree is a Japanese hybrid plum, with a red, almost ruby, skin and juicy red flesh. Ruby Sweet is a huge improvement over old Stanley plums in flavor and disease resistance. In the spring white blossoms are very fragrant, forming juicy plums that ripen in early July.
Enjoy an abundant harvest of Ruby Sweet Plums. The beautiful ruby red fruit is perfect for baking and is also often eaten fresh, canned, or preserved.
This variety is heat tolerant and does well across the South. Plant in full sun in well-drained soil. Ruby Sweet requires a Japanese plum pollinator nearby to set fruit.

A good inch and a half or more at its middle. A nice-sized plum with terrific flavor!
Unfortunately no two of the same varieties can not pollinate, you need another variety that will bloom at the same time such as Methley, Ozark and Morris.
Plums offer a variety of nutritional benefits, making them a healthy addition to your diet. Here are some of the key benefits:
Rich in Vitamins: Plums are an excellent source of vitamins, particularly vitamin C, which supports the immune system, skin health, and wound healing. They also provide vitamin A, which is important for vision and skin health.
High in Fiber: Plums contain dietary fiber, which aids digestion, promotes bowel regularity, and can help lower cholesterol levels.
Antioxidants: Plums are packed with antioxidants, including phenols, which protect the body against oxidative stress and inflammation, reducing the risk of chronic diseases like heart disease and cancer.
Low in Calories: Plums are low in calories, making them a great snack option for those looking to manage their weight without sacrificing flavor or nutrition.
Blood Sugar Control: The fiber in plums can help regulate blood sugar levels by slowing the absorption of sugars, which can be beneficial for individuals with diabetes.
Bone Health: Plums contain minerals like potassium and vitamin K, which are essential for maintaining healthy bones.
Hydration: Plums have a high water content, which helps keep the body hydrated and supports overall health.
Gut Health: The fiber in plums, especially when consumed as prunes (dried plums), can help promote the growth of beneficial gut bacteria, improving digestive health.
Including plums in your diet can contribute to overall health and well-being, offering a range of essential nutrients in a delicious and versatile fruit.

Unfortunately, we do not recommend replying on a wild plum for proper pollination. We recommend planting with either a Methley, Alderman or Santa Rosa plum.
Hi Jessica, Ruby Sweet requires a Japanese plum pollinator nearby to set fruit. The Damson plum is a European plum so unfortunately it won't work.
