You last saw Lindheimer’s senna from some distance as a flowering colony with clouds and blue sky behind it. Now here’s a closer look at a few flowers of Senna lindheimeriana. The yellow in the background came from flowers of yellow bitterweed, Helenium amarum var. amarum.
Today’s view is from a trail along the upper reaches of Bull Creek on September 12.
