California Native Blackberry
Native. California Native Blackberry is used for protection by small animals. The berries are not as yummy as those from the invasive Himalayan Blackberry, but can still be used for jams and pies.
You can tell the difference between the native and the non-native, because the native blackberry has 3 leaves and the Himalayan blackberry has 5 leaves. Also, the native blackberry has much finer thorns than the thick ones of the Himalayan blackberry.
