lilyserrao's Identifications

A small group of E. californica growing in a small patch of gravelly soil at the foot of a more or less S facing wall painted a light (gray) colour.

Note: I originally thought this may be C. caespitosa after checking the photo against what iNaturalist presented as options. While I have always used the common name California poppy for these I found iNaturalist was not the best help in identification.
Great thanks to onyxrat for adding to my knowledge base.
