Quick Answer
Mulberry varieties can be identified based on the shape of their leaves, with common types including the small-lobed leaves of the Morus alba, the large-lobed leaves of the Morus rubra, and the deeply toothed leaves of the Morus nigra.
Leaf Shape Characteristics
When identifying mulberry varieties based on leaf shape, note that the Morus alba (white mulberry) has leaves that are typically 5-7 inches long, with small to medium lobes and rounded tips. The Morus rubra (red mulberry) has leaves that are often 4-6 inches long, with large lobes and a pointed tip. In contrast, the Morus nigra (black mulberry) has leaves that are typically 2-4 inches long, with deeply toothed edges and a pointed tip.
Key Identification Features
Measure the length of the leaves to determine if they fall within the typical range for a given variety. Observe the number and size of lobes, as well as the shape and size of the leaf tip. Additionally, examine the edges of the leaves for any distinctive tooth or serration patterns. For example, the Morus nigra leaf has a distinctive “saw-toothed” edge, while the Morus rubra leaf has a more rounded edge with large lobes.
