Plum Tree, 'Blue Damson'

Grow Your Own Fresh Fruit Trees!
'Blue Damson' has medium-small, dark purple-black plums with yellow-green flesh and a sweet tart flavor. Late producing harvest in early September. 'Blue Damson' is great for jams and jellies. These plum trees grow 15 to 20 feet tall with a somewhat wider spread. Fruit ranges in color from green-yellow to almost black. A higher sugar content makes it possible to sun-dry the fruit without having it ferment at the pit. They are late bloomers and are better adapted to areas with late frosts or cool, rainy, spring weather. Plums grow in many soil types but do best in fertile, well-drained soil.

Plum leaves are simple, oval to oblong and come to a point at the end. The leaf margins are scalloped. When it flowers in the early spring, a plum tree will be covered in blossoms, and in a good year approximately half of the flowers will be pollinated and become plums. Flowering starts eighty days of warmer weather after winter. The shoots have a terminal bud and the side buds solitary (not clustered), the flowers being grouped 1-5 together on short stems.

A plum is a stone fruit tree in the genus Prunus. The fruit has a groove running down one side, and a smooth stone. The 'Damson' plum is an oval, sweet fruit used mostly in jams and was first cultivated in ancient times in the region of Damascus. Careful, early training, annual pruning and shaping are required to insure healthy and productive trees. Prune to avoid formation of V-crotches. Once mature, trees will require little pruning.
