Can you identify this strange flower?

I would describe it has having 50 3/4 inch green "flowers" on
3 or 4 inch stems on the top of a two-foot stalk.

It's in my back yard in northern California, probably put
there by me unwittingly.

I'd appreciate knowing your name for this thing.

It's a Euphorbia (spurge). I don't know the species, but it looks
similar to Euphorbia characias and Euphorbia x martinii
