What vegetables were grown in the area in 1703?
Colonial kitchen garden and field vegetables would have been root crops: carrots, parsnips, turnips, radishes, cabbages, beets. Also peas, beans, spinach, lettuce, pumpkins, gourds, melons (more commonly grown in the South) SEE: Judith Sumner’s American Household Botany : a History of Useful Plants (chapter 3)
Am also sending you a scan of pertinent pages from Rudy Favretti’s Colonial Gardens. Didn't include information on fruit growing, but certainly people would have done that as well.
