Arctostaphylos spp. – Sonoma, California
These three photos were taken from different wild plants growing in the hills just outside the town of Sonoma. There are around 30 Manzanita species and sub-species listed for Sonoma County, so it becomes challenging to be sure when trying to identify species growing outside of cultivation. To me they look like A. densiflora.
Any confirmation or correction appreciated in the comment forum.
