Prunus domestica ssp. insititia 'Blues Jam'

This amazing tree produces so many fruits, they look from a distance like thick, dark blue ropes covering the branches. These small Damson-type plums have a sweet/tart, dense flesh and the freestone fruits make great preserves. The astringency common to Damson-style fruits is easily moderated by freezing and thawing the raw fruit before using, or by blending with other fruits or varieties of plums. 

The tree is reliably self fertile, upright, disease resistant and easy to grow, setting huge, annual crops in late September. From Cornell Univ in NY.
