Black mulberry + Swamp cabbage

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.

Ipomoea aquatica is a semiaquatic, tropical plant grown as a vegetable for its tender shoots and leaves. It is found throughout the tropical and subtropical regions of the world, although it is not known where it originated. This plant is known in English as water spinach, river spinach, water morning glory, water convolvulus, or by the more ambiguous names Chinese spinach, Chinese convolvulus, swamp cabbage or kangkong in Southeast Asia. Occasionally, it has also been mistakenly called "kale" in English, although kale is a strain of mustard belonging to the species Brassica oleracea and is completely unrelated to water spinach, which is a species of morning glory. It is known as phak bung in Thai, rau mu?ng in Vietnamese, trokuon in Khmer, kalmi shak in Bengali, kangkung in Malay and Indonesian and hayoyo in Ghana.
