Continuing with murderer's row, garlic mustard and man have been involved for at least 6000 years, and probably since around the time we first browsed a meal on land. The leaves are still used for flavoring and salads in some places in Eurasia. The flavor genuinely does combine mustard and garlic. Although it is not a preferred browse. And that is one of the problems. Once it gets into your woodlot, there is not much to slow it down. It will quickly take over. Your spring ephemerals will be gone. No more trilliums, or bloodroot, or violets. Removing it is very labor intense, and will take years of persistence. If your neighbor has some, you will never be done.
