Beach Plum (Prunus maritima) Plant.
1 seedling plant, 6”+ tall.
This shrubby plum species, not only tolerates poor soils (as long as they are well drained) but resists insects and disease better then any other Prunus species i have grown. The fruit is about the size of a sweet cherry (with a smaller stone) and makes excellent jams, pies etc. Some individuals are also tasty out of hand.
