I have taken a picture of the weed in my garden that is driving me crazy, and I can't for the life of me find anything on the internet that looks like it! Unfortunetly, the purpose of my garden is to provide a safe place for my rabbits to play, so I cannot use weed killer. So this certain plant keeps coming back no matter what I do! I also want to eventually plant cabbages and lettuces outside so want to keep the soil in the best condition without chemicals. I don't really have a problem with this particular plant being in my garden providing it if safe for my rabbits if they decide to nibble on it. But without knowing what it's called I don't know whether I can leave it to my rabbits to chew away at, or keep fighting it off!

Please help
