The Catonsville Historical Society has laid out a knot garden on the Townsend House property, in Catonsville, Maryland. The garden was installed with the help of the Baltimore County government, and the Commission on Arts and Sciences. The garden provides a charming focal point to the grounds. A knot garden, also called a parterre, uses elaborate patterns of low interlacing or miniature tightly clipped hedge work, interspersed with colored materials or plants, to create the illusion of crossing over one another, thus giving the appearance of knots. To achieve the correct appearance, strict geometry must be followed, making the creation of a knot garden a detailed project. The Knot Garden serves as a reminder of the beautiful gardens that graced such Catonsville estates as the Farmlands home of Gustav Lurman Sr., where Catonsville High School stands today.
