Thank you Scott! I really appreciate you looking into it :) Calflora is wrong as well. I'll update the ID with O. stricta.

I did a bit more online reading and it looks like gardeners report O. stricta growing, sometimes profusely, in some parts of California. The USDA PLANTS database is by far the best resource for finding a plant's distribution, but it isn't perfect. Looks like they're wrong on this one.

Hi Scott, I agree it looks like Oxalis stricta. Does O pes-caprae even have the same seed pods? I can't explain why stricta would be growing here but the resemblance is amazing.

That's one of the yellow wood sorrels, genus Oxalis. I'd say Oxalis stricta (, but the USDA doesn't list it as growing in CA, so probably O. pes-caprae.
