It is a former estate garden featuring annuals, roses and wildflowers and an extensive rockery. It is located on Wilket Creek, one of the tributaries of the Don River West Branch. The estate's title was once held by Alexander Milne, a Scottish weaver who settled there after the War of 1812 and left in 1832. Although the property remained in the Milne family, it was left in neglect. The land and the woolen/saw mills were bought by Rupert E. Edwards in 1944 and he created a magnificent garden there. He sold the property to the Municipality of Metro Toronto in 1955 to become a public park, and it became Edwards Gardens in 1956. The Civic Garden centre was relocated from another Milne property, the Milne home on Old Lawrence Avenue.
Edwards Gardens is one of several parks located along Toronto's ravines, many of which are connected by hiking and cycling trails, and connected to the shores of Lake Ontario. The park's manicured lawns and flower beds make it a popular destination for wedding parties to take photographs.
