While all plum trees can be pollinated by insects, there are a number of varieties that are self-pollinating. These trees will produce their own fruits with no help from insects and may cultivate a good crop due to their location near another plum tree of a different cultivar. These trees are also known as "self-fertile," but they can be among the most difficult trees to manage if you are starting a plum tree grove on your property.
This type of plum tree was first seeded in England in the mid-1800s and features plums that are larger than the fruits offered by most other plum trees. These fruits are known for their good taste and offer a fleshy color from green to yellow. The tree also produces juicy fruit that appears in the later summer or early fall, usually around the middle of September.
This type of plum tree is not very common throughout the world, but was first seen in England. Like the Victoria plum, it also produces fruit in the middle of September. The plums will stay fresh for as long as a month at a time. The plums are black-blue in color and are larger and more oval-shaped than many varieties. The Marjorie Seedling usually produces a large crop.
The Czar plum is among the many self-pollinating plum trees that can be seen in locations around the world. This tree is a mix between the Prince Englebert and Early Prolific plum tree varieties and produces a plum that's small to medium in size. The fruit from these trees is roundish in shape and is known for a strong flavor. The plum is greenish-yellow and provides a heartier eating experience than many other varieties of plum.
The Blue Tit plum tree is a self-pollinating type that was first bred in 1995. This tree features a plum with blue skin, which is rare in the world of plums, and has a normal oval-shaped body. The Blue Tit plum tree produces a large crop in most cases and is most fertile in the hot month of August. This is the kind of plum that is commonly sold in fruit stands or grocery stores.
