Description

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.

Needlegrass is just beginning to flower; this is from very high on the hill, in full sun. I don't know whether this is Stipa lepida, cernua, or pulchra, but it's lovely to see the long, delicate needles flashing in the breeze. At the foot of the clump is last fall's goldenrod.
