North Haven Gardens has a rich history here in Dallas. In 1951, Ralph and Muriel Pinkus founded NHG as a small nursery on nine acres of grassland along Northaven Road north of Dallas. They began with landscaping, but quickly included selling retail plants to anyone who would make the drive. With a commitment to quality and value for their customers, the nursery has grown into one of the most respected horticultural ventures in the area.

Also, in the early 1970’s, Ralph worked through the North Dallas Chamber of Commerce and the City of Dallas Park Department to create an Arboretum and Botanical Garden for Dallas that would demonstrate what homeowners could do in their own yard.
