The black mulberry (Morus nigra) is a species of mulberry native to southwestern Asia, including Iran, Afghanistan, and Pakistan. It is a small to medium-sized tree that grows to be about 20-30 feet tall and has a round, dense canopy. The leaves of the black mulberry are dark green and glossy on the top, and paler and slightly hairy on the bottom. The tree produces small, white flowers in the spring, which are followed by black, juicy fruits in the summer.
The black mulberry is relatively fast-growing and can reach its full size in about 10-15 years. It prefers well-drained, fertile soil and full sun, but can tolerate partial shade. It is also winter hardy and can withstand temperatures down to about -10°F.
The fruits of the black mulberry are edible and can be eaten fresh or used in jams, jellies, and other preserves. They can also be dried and stored for later use. The leaves of the black mulberry can be fed to silkworms, and the wood of the tree is strong and durable, making it suitable for a variety of uses.
In addition to its edible fruits, the black mulberry has several other uses. Its leaves can be used as a natural fertilizer, and the tree can provide shade and wind protection in gardens and farms. The black mulberry is also a popular food source for birds and other wildlife.
