Robert O. Davenport and Sons is a family-owned farm market, greenhouse, and wholesale vegetable farm located in Stone Ridge New York. They have been farming since Isaiah Davenport moved across the Hudson River from Duchess County to Ulster in the 1840's but the farmland was in agricultural use before the arrival of European settlers. A conservation easement that permanently protects the land assures that it will be in agricultural use in the future, as well.
