Some people think it is a hybrid of R. nutkana. It is certainly very different from a Santa Cruz, California wild plant of a double form of R. californica.

I am curious about this rose with mahogany-red canes, so-called Rosa californica plena. The shape of its petals is distinct from that of the local Rosa californica. The six different thickets of R. californica that I've photographed all have cordate petals - meaning slightly heart-shaped with an indent or notch in the upper edge. The petals of Rosa californica plena are largely tear-drop shaped, although a few do have a notch. They have a distinct white tip at the base, forming an indistinct white eye. The arrangement of the stamens is irregular around the pistil. The blooms of Rosa californica seem to have a perfect disk with a perfect circle of stamens surrounding it.

Rosa californica plena is in full bloom right now, whereas Rosa californica is just beginning its long bloom season, which here ranges from late May through August, into September, with scattered bloom even later.
