(horticulture) A garden with paths between such flowerbeds.Examples: "Parham House, near Pulborough in West Sussex, has a four-acre walled garden that was restored in the Twenties and has been maintained at a high level ever since. It is divided into four areas, one of which is filled by the cut-flower borders and a box-enclosed parterre. […] It is traditional in a parterre to mix flowers and veg, but this relaxed jungle of productive plants, packed in tight together, is lusher and more beautiful than the more usual Villandry style, where single or pairs of plants are used."

A short time afterward at the opera Gerald dragged him into a parterre to say something amiable to one of the amiable débutante Craig girls—and Selwyn found himself again facing Alixe."
