Red Mulberry (Morus rubra): Native Sweet Fruit for Wildlife and People

Red Mulberry is a native North American tree that produces delicious, blackberry-like fruits beloved by birds, mammals, and humans alike. Morus rubra (family Moraceae) ranges from the Great Lakes to the Gulf Coast, thriving in rich, moist woods and floodplains.

Fruit and Tree Characteristics

The fruits are aggregate drupes, 1-1.5 inches long, ripening from red to deep purple-black in early summer. They're sweet, juicy, and richly flavored—considered superior to the introduced White Mulberry (M. alba). The leaves are polymorphic (variable—lobed to entire), 3-7 inches, rough-textured above, softly hairy beneath. The tree grows 30-60 feet tall with a broad, rounded crown. The bark is orange-brown, fissured.

Ecological Importance and Cultivation

Red Mulberry is a wildlife powerhouse: over 50 bird species eat the fruits, plus raccoons, opossums, foxes, and squirrels. The foliage hosts numerous caterpillars. It's also a host for the Mourning Cloak butterfly. For humans, the fruits are excellent fresh, in pies, jams, wine, and dried. The wood is durable, used for fence posts and furniture.

It prefers rich, moist, well-drained soil and full sun to part shade. It's dioecious (male/female trees)—plant several for fruit. It hybridizes readily with invasive White Mulberry, threatening genetic purity. In cultivation, choose named female cultivars or seedlings from known Red Mulberry parents. It's hardy to zone 4.
