Originally introduced by naturalist Oscar Clark, when fully ripe produces loads of medium-size, black fruit that are considered among the most flavorful. The early-ripening fruit can also be eaten at the red stage and has a 'raspberry' flavor. It is self-fertile. It is a fast growing, easy-care shade tree. 
 
The Oscar mulberry tree is recognized for its unique berry-like fruit that is edible both in its unripe red stand and its ripe black stage. When unripe, the fruit is said to taste like a raspberry with a blackberry texture, whilst, when ripe, it is said to offer a sweeter and more aromatic floral flavor. 
 
The Oscar mulberry tree is known to start bearing fruit at the age of 2 to 3 years. It’s a relatively small tree that grows to around 25 ft. This variety of trees is ideal for growing as an ornamental plant as it is disease and pest-resistant.
