(The species with red berries are not toxic; poison sumac has white berries.) The red fruits ripen in late summer, when they may be placed in a jar of hot or cold water and allowed to sit for several hours to make a sort of lemonade. By autumn, the remaining berries make an interesting nibble, with their burst of sour flavor, but they have lost much of their Vitamin C to the rain, which leaches it from the fruit. Later in the season, most of the clusters are inhabited by spiders. Birds, however, will eat the fruit throughout the winter."
