In The Garden: Green, Small, Geometric, Soft

Near Santa Maria, California
Found this in the garden in a few different places
Wondering what it is so we can do more research on potential uses as well as teach kids about what is in our garden :)

Note: My hand is small - roughly 17cm (6.7in) from wrist to tip :)

Thanks in advance!

 

Its one of the little, rather weedy euphorbias, like Euphorbia peplus.

 

♥ Thank you, Geoff!!!
