Black mulberry is a fast-growing, rounded deciduous tree with inconspicuous flowers and edible fruits. The flowers are pale green and tiny and appear in clusters that produce bead-like fruits attached to a fleshy core in an oblong cluster. The clusters go from red to black as they mature, and resemble blackberries, but are only mildly sweet and flavorful. Planted mainly for shade and its tolerance of hot, dry conditions, black mulberry is also valued by some gardeners as a pie fruit and as food for birds. A mature tree produces huge numbers of fruits which fall when ripe, so avoid planting the tree along paths, paving, patios and decks. The tree is prone to diseases which disfigure its handsome heart-shaped leaves. It is also a weedy tree, producing many seedlings.
Like other species in the mulberry genus, black mulberry grows best in full sun on average, well-drained soil, but it tolerates almost any well-drained soil. Train it to a single trunk and high branches to reveal its handsome bark.
