Sand Creek Road

Sticky monkey flower is a small shrub with vibrant orange flowers. It is common and widespread in Northern California, but not so common in Colusa County. It does grow on the sandy floodplains along Sand Creek beyond Green Road. Western morning glory, a native, grows there too. California rose grows along the channel, abundantly in some areas. Several of the widespread lilies are flowering along the road including twining snake lily, yellow mariposa lily, superb mariposa lily, and harvest brodiaea. Harvest brodiaea, one of the latest lilies, is in full flower along Sand Creek, but has not yet started to flower in other areas.  Fork toothed ookow, a lily related to blue dicks and twining snake lily, is also flowering along the road. It is not common in the county. Fringed sidalcea is common as scattered plants, and in more dense populations in a few areas. Wooly sunflower, foothill penstemmon, and Indian paintbrush are common here as along many of the foothill roads. The paintbrush is wooly paintbrush; wavy leaved paintbrush is also common in the county. Away from the creek much of the area is dominated by chamise. It has started to flower. Parish’s nightshade and pacific pea are a couple of chaparral plants along the road that are not so common.
