Thorny weed ID
I have a thorny weed in my vegetable bed. The leaves are quite pretty Varigated green red/purple BUT with thorns ! I try to go below the soil to pull it up but I seem to get stuck by the small ones that hide in my lettuce beds (with the red leaf lettuce). I want to rid my beds of it but it is a painful weed . Any Idea what it is . It didn't show up until the weater was getting warmer.
