A lemon plum is a rare fruit imported from Chile. It resembles the taste of a plum, and is very sweet and juicy. The fruit has a similar shape to that of a lemon, except one end is rounded and the other end has a nipple. When unripe, they have a bright yellow color, and are sour. As they ripen, their color changes from yellow to a golden orange and then finally to a dark sunset reddish purple when ripe. They have a slightly floral, very fragrant smell. Their peak availability in the United States is very short and is typically within the month of February.
