Quick Answer
Red mulberry trees (Morus rubra) are native to eastern North America and are characterized by their edible red fruit. White mulberry trees (Morus alba) are native to Asia and have been naturalized in many parts of the world, producing edible white fruit. Both trees share similar characteristics, but have distinct differences in their growth habits and fruit.
Identification
Red mulberry trees typically grow 30-50 feet in height, while white mulberry trees can reach heights of 50-70 feet. Red mulberry trees have a more oval-shaped crown, with branches that grow at a 45-degree angle, whereas white mulberry trees have a more irregular crown shape. In order to identify the tree, observe the color and size of the fruit. Red mulberry fruit is typically 1-1.5 inches in diameter, while white mulberry fruit is larger, measuring 2-3 inches in diameter.
Growth Habits
Red mulberry trees tend to grow in a more compact, dense manner, while white mulberry trees have a more open, spreading habit. This difference in growth habit can be attributed to the fact that red mulberry trees are more tolerant of shade, and are often found growing in woodland edges and floodplains. White mulberry trees, on the other hand, are more adaptable to a variety of soil conditions and can thrive in full sun or partial shade.
Edibility and Nutrition
Both red and white mulberry fruit are edible and rich in nutrients, including vitamins A and C, potassium, and fiber. The fruit can be eaten raw or cooked, and can be used to make jams, jellies, and other products. However, be aware that the white mulberry fruit may be slightly sweeter than the red mulberry fruit, and may have a more delicate flavor.
