Winter greens Winter greens Winter greens are green leaved vegetables, closely related to the cabbage, that are seasonably available in winter. Common vegetables described as winter greens are chard, collards, rapini, and kale. William Morgan classed Brussels sprouts, savoy cabbages and several varieties of kale as winter greens. Morgan grew these vegetables and compared their hardiness, identifying which species were most suitable for growing through cold winters. He presented his findings to the Horticultural Society of London in 1818.

Fat choy Fat choy Fat choy (; "Nostoc flagelliforme") is a terrestrial cyanobacterium (a type of photosynthetic bacteria) that is used as a vegetable in Chinese cuisine. When dried, the product has the appearance of black hair. For that reason, its name in Chinese means "hair vegetable." When soaked, fat choy has a soft texture which is like very fine vermicelli. Fat choy grows on the ground in the Gobi Desert and the Qinghai Plateau. Over-harvesting on the Mongolian steppes has furthered erosion and desertification in those areas. The Chinese government has limited its harvesting, which has caused its price to increase.
