Mongolian Mulberry

Morus mongolica
Moraceae (Mulberry family)
The Garden’s example of the Mongolian Mulberry, Morus mongolica, very rare in cultivation, is a champion tree. It is an impressive sight amongst the Mulberry family on the south-western corner of the Systematic Beds.
In autumn, the toothed, elliptic leaves turn a very deep purple, almost black. Its fruit turns almost black and is edible, but is not so flavoursome as those of the Black Mulberry, Morus nigra, which can be found nearby.
