An Overview of Mulberry Tree
Mulberry, whose scientific name is ‘Morus spp,’ belongs to the family of Moraceae and is a deciduous fruiting tree. It is native to the Asian and North Americans.
Mulberry trees require full sunlight for growth and can be tolerant of drought. It is a non-toxic plant and, when fully mature, can grow as high as 80 feet. Pests of mulberry are caterpillars and scale insects.
Varieties of Mulberry Tree
Mulberry comes in three varieties, otherwise known as forms. These three different forms vary slightly from one another but require the same growth and care tips for them to thrive.
Various forms or varieties of mulberry are the white mulberries, the black mulberry, and the red mulberry. We shall discuss each of these varieties in detail below:
White mulberry, also known as Morus alba tatarica, originated from China and are easily grown. White mulberries start as white fruits but later on grow to become dark purple. They are the tallest of the three varieties of mulberry, growing up as high as 80 feet.
White mulberry plants are easily adaptable as they can thrive in poor soil conditions and areas with partial shades. Depending on the cultivar, white mulberry can take up any shape. Some mulberry trees have a weeping habit, while others grow into a pyramid shape.
Riviera is a cultivar of white mulberry and produces fruits that juicy, fleshy and sweet. It originates from California and has a long harvest period of April down to June.
Black mulberry, scientifically known as Morus Nigra, originates from China and thrives well in warm areas. Black mulberry cannot thrive in any region whose temperature is lower than that of USDA hardiness zone 6. It also does not survive in winter.
Black mulberry trees are usually the smallest of all the three varieties of mulberry and can only grow as high as 30 feet. Growing black mulberry usually requires constant care and pruning to enable it to grow into a definite shape; otherwise, it will grow into a bush rather than a tree.
Cultivars of black mulberry include:
Kaester: This cultivar originates from LA, USA. It bears a lot of fruits that are usually up to 1.5 inches in length.
Black Persian: This bears large juicy fruits that are a little over an inch long.
Shangari-la: This cultivar is ideally grown in the Southern United States. It is native to Florida and thrives in warm areas. Shangari-la is notable for its unique foliage with humongous heart-shaped leaves. It bears large black mulberry fruits.
Red mulberry, also known as Morus rubra, is regarded as an American mulberry tree. This cultivar is native to the United States and was reportedly first grown along the Gulf Coast to Massachusetts.
Red mulberry trees thrive in warm areas, and unlike the white mulberry tree, it thrives in rich fertile soils and can grow as high as 70 feet.
Red mulberry has quite a similar appearance with black mulberry, although it has smaller buds. In recent times, red mulberry trees are being crossbred with white mulberry trees to form new cultivars.
Cultivars of the red mulberry tree are Pakistan and Russian. Pakistan originates from Pakistan and thrives in warm weather, although it can do well in winters. Pakistan bears very large fruits that measure up to 3.5 inches long.
Russian originates from China. It grows for only about 35 feet in height and is used as a windbreaker because it is very tolerant of wind. Russian cultivar is one of the hardiest cultivars of mulberry.
