Eriogonum umbellatum, Sulfur Buckwheat

This is called the Sulfur Buckwheat. The Latin name for it is Eriogonum umbellatum. It is a striking flower in the late spring. There are large populations that turns a whole hillside yellow. the plant is fairly short, but the flower spikes may get twelve inches tall. In the garden and in the desert it grows with only the water that falls from the sky. In my area that may be 10-20 inches of annual rainfall.
