White Mulberry: Morus Alba Australian Growing Guide

Morus alba, commonly known as the White Mulberry or silkworm mulberry, is a tree that can reach a height of 18m and a width of 10m. In Australia, the White Mulberry flowers in November, with its seeds ripening from January to February, the same as other mulberry tree varieties in Australia. 

The plant's flowers are monoecious, meaning both male and female flowers are present on the same plant, and they rely on wind for pollination.
