Thanks to all who posted here and the ID Janet. Like pardalinum I see it, I pull it. I view it in a different light after reading your discussion. Even when large the roots seem to be fairly shallow, at least it's easy to pull. I think I'll start treating
Spotted Spurge (Euphorbia maculata) like
Common Purslane (Portulaca oleracea), leave it alone here and there. Your photos are quite nice Lyn, would you mind if I added them to the database?
