While it's not clear whether gardens were for pleasure or were for utilitarian purposes it's clear that some gardens were intended primarily to be a delight to the senses, and others for their end products.
Most every manor, abbey, and great estate would have utilitarian gardens, farm fields, and perhaps woods and even vineyards or orchards. In addition there would be some sort of pleasure garden. (Vineyards were less prevalent and less successful in Northern Europe than Southern Europe but grape vine plantings were useful for the production of verjuice and perhaps grapes for eating even when wine quality was not achieved.)
