Grow a fast-growing and productive fruit tree with Black Mulberry seeds. This heirloom is celebrated for its abundant crops of sweet and juicy, dark purple-black berries that look much like an elongated blackberry. The fruit is delicious, with a perfect sweet-tart balance that is wonderful for eating fresh or for making pies, jams, jellies, and wine. The tree itself is a vigorous grower with a handsome, rustic form and large, heart-shaped leaves, providing beautiful shade in the summer.
