The Moonberry Vine is a silver-leaved climber that produces dark fruit after absorbing a complete night of reflected sky light.
Appearance
The vine has curling tendrils, silver-green leaves shaped like narrow crescents, and clusters of nearly black berries. A pale crescent forms naturally on each ripe fruit as sugars collect beneath the skin.
Reproduction
Flowers remain closed during direct sunlight. They open after sunset and track reflected light from clouds, windows, and moons. Fruit ripens after five clear nights or nine cloudy ones.
Food use
Moonberries are cooked into oatmeal, glaze, yogurt, and school desserts. Ripe fruit tastes mildly sweet and cool; unmarked fruit is sharply bitter and is not served.
Cultivation
Gardeners train the vine around pale metal supports and leave one side exposed to the night sky. Indoor crops use mirrors rather than artificial lamps.
