growing in rocky soil, off-trail.
This plant was photographed at the edge of the Serpentine Prairie in Redwood Regional Park. Although this is at a location where Presidio Clarkia (C. franciscana) is found, the flower color here seems too rich for that species. Help with ID would be appreciated.
Close up, the deep red at the center bowl of the flowers becomes apparent. The reserve has three different observed species of Clarkia: C rubicunda, C unguiculata , and C purpurea. C unguiculata's shape is distinctive and is NOT a cup as these, and C purpurea is paler at the center.
sepals 4, fused. 6" high. pink.
