The garden's initial site was acquired in 1967 by a local retirement home, with the aim of creating a farm. In 1993 its first arboretum specimens were planted with residents' help, and in 1999 the site expanded by seven hectares. In 2001 its maple collection received a national commendation, and in 2004 the garden opened its Himalayan valley and collections of medicinal plants from Nepal and Yunnan.
