Valentine Pomelos Grapefruits are usually round with a protruding neck at the stem end, similar in shape to a pear. The rind is dark yellow and easy to peel, while the pulp inside is bright red. The fruit has a moderate amount of seeds, and is juicy and sweet especially compared with more acidic citrus. Other pomelos are a light green color when ripe, but Valentines are ripe when their rind is a uniform yellow.
