There is a large patch of Yellow Flag Iris growing and blooming on the west bank of Johnston Creek (Beaver Pond). This is in the Brookhaven Woods Natural Area, a riparian corridor. This can be reached by entering the Brookhaven Woods Natural Area from the SW Ivy Glenn Ct. entrance next to 15127 SW Ivy Glenn Ct Beaverton OR 97007. Also, there is a large stand of Bamboo growing on the east bank almost opposite the Yellow Flag Iris location but a bit to the south of the Iris.
