Hector, It's at the transition zone next to the foothills in Sylmar, CA... It's basically Big Tujunga Creek. It flows year round, regardless of the drought, lol
Wsdstan, believe it or not, all the plants I showed can be eaten, used for medicine, or have other utilitarian uses.
In the water shots, it is rife with watercress, veronica, umbrella plant, cattail, knot weed, monkey flower, curly dock and others I can't recall. The surrounding trees are willows, cottonwoods, and alders.
The close ups are :big white trumpet flower is Jimson Weed a known and powerful narcotic. The white and brown cluster head is California Buckwheat and is used to make flower for hotcakes, breads, etc. The plant with the whitish stem is Everlasting and has an amazing maple syrup aroma. The green one with opposite whorled like leaves is black sage, used in cooking and to treat stomach ailments. The spiky seed one is cocklebur and makes a good field expedient velcro. The white dandelion like seed head is prickly lettuce and totally edible
I guess the answer is yes weeds to some, but useful to others, lol
