[Columbia River Gorge Wildflower Reports]

Currently Blooming Wildflowers in the Columbia River Gorge

Tom McCall Point Trail

July 4, 1998

Wildflower bloom in the eastern Columbia River Gorge is starting to become somewhat limited to areas with moisture, either riparian habitats, those on north-facing slopes, or at higher altitudes on the ridgetops. Grasses are becoming browner with interesting seed heads, and many of the wildflowers now have beautiful seed pods.

Those plants that bloom during the summer, need dry conditions and probably lots of sunshine. They typically are hairy plants, often silver or silvery-blue in color to help retard moisture loss and reflect sunlight, hence lowering their temperature.

Flower bloom should again begin to rise in late summer into fall as the shrubby members of the sunflower family begin to bloom. Those areas with sagebrush or goldenweed, or rabbitbrush will be ablaze with yellow at that time!
