Life Style / Wine Grapes / Martha: Seedling of Concord introduced around 1868. Self-fertile, it ripens around a week earlier than its parent to give a medium size berry that has a light-green, with a touch of yellow, skin. Less foxy than its parent it was often mistaken for the Niagara variety although it reportedly does not keep or ship well. Due to the popularity of competing varieties it was gradually displaced and now sparcely grown, if at all.
