Scotch Broom

I took this shot because it shows an example of the Scotch Broom (the yellow bushes) growing along the roadway near Port Townsend, Washington. Scotch broom was introduced as a garden ornamental by early settlers of the Pacific Coast. It has spread far beyond the bounds of cultivation and now covers many acres west of the Cascades from British Columbia to California. Wherever it grows, this aggressive plant spreads to form pure stands at the expense of desirable grasses, and young trees. Because it is a threat to native plant species and indirectly to animals that feed on the displaced plants, Scotch broom is a Class B noxious weed in Washington and Oregon.
