Just Say No to Abuse Declaring War on Terrorism. Sheep sorrel , Wild plants, Edible Sheep sorrel , Rumex acetosella, grows profusely in my yard and gardens here in Quebec.
Sheep sorrel is Eurasian in origin and has made it's home all across North America.
Look for the arrow shaped and lemon flavored leaves in disturbed areas, gardens and high acid soils in areas spanning as far south as Oklahoma and as far North as Alaska. Personally I allow it to spread since it makes a nice ground cover when mowed. Richters does sell seeds if you need an on-line source. Select only deep green leaves when harvesting, discarding any damaged or yellowing leaves. I harvest throughout the year and have found sheep sorrel to be persistent throughout the winter where the snows are lighter close to the house.
