Native blackberry rivals poison oak as the most common understory plant in the Hillside Natural Area. This patch is in sun near willows along a creek, but it also flourishes under oaks. It is easily recognized by having prickles rather than thorns -- if you can grasp it without pain, it's native blackberry.
