A garden festival is characterized by its nature as a garden exhibition event. The Seoul Garden Festival was held to expand garden culture, increasing citizens’ quality of life, and also to achieve urban regeneration through discovery and development of features of various gardens in Seoul. Mother’s Garden of Memory is based on the motif of the gardens tended by mothers in the past, and inspires recollection of related memories and stories. Gardens tended by mothers in the past can be encountered today in everyday life as practical living gardens. Facilities and suitable space sizes for a living garden were selected based on previous research results. The exhibition garden was designed to include a fruit tree hill, medicinal plant/herb garden, and butterfly garden in its planting space; a vegetable garden in its multi-purpose space and production space; a pond in its waterscape space; and a seating wall in its resting space. Additionally, the garden’s plants consisted primarily of species that were suitable for the characteristics of each space, could be tended practically, and could be accessed easily. Finally, a garden management plan was established to provide a model for living gardens, ensuring that these gardens could be continuously sustained.
