|Morus rubra is a large deciduous tree reaching 40 to 70 feet in height, with a 40 to 50 foot spread. It has a more open habit than White Mulberry, and large, attactive, dark green leaves. In fall it turns a mellow yellow. The mulberries are red to dark purple, edible and juicy, if you can get to them before the birds. Native from Massachussetts to Florida, west to Michigan, Texas. Introduced 1629. It is not as tolerant as White Mulberry of poor soil conditions, preferring rich, moist and fertile ground.
