Sang Zhi (Morus alba – White Mulberry) is a species native to Northern China where its cultivation has been so long that it precedes any recorded history of it. It is a short lived tree on which the silkworm feeds. Other species are often confused with it such as the Black Mulberry (Morus nigra) but it is easy to tell from the leaves of the White Mulberry which species it is because it has no hairs on the lower leaf surface whereas the Black Mulberry does.
Its fruit is poisonous when unripe.
