Did you know?

California buckthorn is often called coffeeberry because its berries (fruits) contain two nut-like seeds that look like coffee beans. After a fire or other disturbance such as cutting that removes the above ground stems, etc., the plants sprouts vigorously from buds on the root crown. Individual plants can live 100 to 200 years.
