was Unknown Oxalis, now Oxalis purpurea

I have both Lavender and Pink forms - it’s the Lavender one which is most aggressive. Wouldn't mind some white ones ...

My gophers like to move the O pes caprae around, or at least stash 100's in underground chambers and then not live long enough to eat them.

I agree that this looks like Oxalis purpurea. There probably are forms that aren't aggressive, but my experience in coastal Northern California has found it to spread rapidly and even tiny ones have more tiny ones on the stolons if you don't get pull them out quickly. I grow a couple of nice forms in pots and on nice days before the soil gets to dry to dig, task myself to dig up a 100 of various sizes. I don't  have gophers, but some years I find new patches of Oxalis purpurea where it didn't grow before. My garden has a lot of trees and shade so I get mostly leaves.
Diana Chapman once remarked this would make a nice lawn and that is probably true if you didn't want anything else and wanted green for many months of the years and the knowledge that if it dies back in summer it would come back when it started to rain again.
