Black mulberry + Japanese persimmon

Morus nigra, the black mulberry, is a species of flowering plant in the family Moraceae, native to southwestern Asia, where it has been cultivated for so long that its precise natural range is unknown. The edible fruit is dark purple, almost black, when ripe, 2-3 centimetres (0.8-1.2 in) long, a compound cluster of several small drupes; it is richly flavoured, similar to the red mulberry (Morus rubra) but unlike the more insipid fruit of the white mulberry (Morus alba). Black (Morus nigra) mulberries are thought to have originated in the mountainous areas of Mesopotamia and Persia and are now widespread throughout Afghanistan, Iraq, Iran, India, Pakistan, Syria, and Turkey, where the tree and the fruit are known by the Persian-derived names toot (mulberry) of shahtoot (شاه توت) (king's or "superior" mulberry), or, in Arabic, shajarat tukki. Jams and sherbets are often made from the fruit in this region.

Diospyros kaki, better known as the Japanese Persimmon, Kaki Persimmon (kaki [?]) or Asian Persimmon in North America, is the most widely cultivated species of the Diospyros genus. Although its first published botanical description was not until 1780, the kaki is also among the oldest plants in cultivation, known for its use in China for more than 2000 years. In some rural Chinese communities, the kaki fruit is seen as having a great mystical power that can be harnessed to solve headaches, back pains and foot ache .
