The only shrub or tree species native to all 48 contiguous states. One cultivated variety has dissected or bipinnate leaves. Raw young sprouts were eaten by the Indians as salad. The sour fruit, mostly seed, can be chewed to quench thirst or prepared as a drink similar to lemonade. It is also consumed by birds of many kinds and small mammals, mainly in winter. Deer browse the twigs and fruit throughout the year.
