Wax gourd + Black crowberry

The winter melon, also called white gourd, winter gourd, tallow gourd, Chinese preserving melon, or ash gourd, is a vine grown for its very large fruit, eaten as a vegetable when mature. It is the only member of the genus Benincasa. The fruit is fuzzy when young. The immature melon has thick white flesh that is sweet when eaten. By maturity, the fruit loses its hairs and develops a waxy coating, giving rise to the name wax gourd, and providing a long shelf life. The melon may grow as large as 80 cm in length. Although the fruit is referred to as a "melon," the fully grown crop is not sweet. Originally cultivated in Southeast Asia, the winter melon is now widely grown in East Asia and South Asia as well.

Empetrum nigrum is a species of crowberry known as black crowberry which is native to most northern areas of the northern hemisphere, as well as the Falkland Islands in the southern hemisphere. In gardening, it can be grown in acidic soils in shady, moist areas. It can be used for the edible berries, for a purple dye, or as a ground cover. The metabolism and photosynthetic parameters of Empretrum can be altered in winter-warming experiments
