Founded by Irish immigrants, Wilson Farm has been in operation at its present location since 1884. James Alexander Wilson, W.M. Wilson, and brother-in-law George Reynolds came to Lexington from Enniskillen, Ireland. Here they were able to buy 16 acres of land and rent some of the surrounding fields for farming. James A. Wilson was the salesman, and the other partners worked the farm, growing vegetable crops and plants.

Today the farm has expanded from 16 acres to 33 acres in Lexington; and to an additional 500 acres in Litchfield, New Hampshire.
