commissions included designing the lily pond for Coombe Cottage, Dame Nellie Melba's residence in Coldstream, in the Yarra Valley Ranges; Durro l for Mrs Stanley Allen at Mount Macedon (the garden remains though the house was destroyed by fire on July 11, 2018); Rock Lodge garden for Mrs P.F. O'Collins in Frankston; Cruden Farm garden for Mrs Keith Murdoch (later Dame Elisabeth), Langwarrin and the Marshall Garden in Eaglemont. One of her most intact NSW commissions is Markdale, Binda (). Walling's expertise as an artist enabled her to produce watercolour plans to convey to clients the ambience of the finished gardens she intended to create. Her plans from the 1920s and 1930s show a strong architectural framework with 'low stone walls, wide pergolas and paths – always softened with a mantle of greenery'. She later drew inspiration from the Australian bush, creating a more naturalistic style with boulders, rocky outcrops and indigenous plants. In small suburban gardens, Walling created garden 'rooms' to make the garden appear far larger than it actually was. Her designs were heavily influenced by her experience of the Devon countryside as a child and designers such as Gertrude Jekyll. The houses of American architect Royal Barry Wills (renowned for his Cape Cod designs) and Lewis Mumford’s books, The Culture of Cities and The Image of the City, also provided early inspiration. Conservationist In the mid-1940s Walling concentrated her interest in native plants which she had begun using in domestic gardens in the 1920s. In the 1950s, she became interested in the conservation of roadside vegetation and was a prolific writer in the press on the subject as well as her 1952 book The Australian Roadside. According to Trisha Dixon, Walling was an important influence on Australian gardening, steering tastes away from an Anglo-centric heritage towards a respect for the Australian climate and landscape. In 1967, she moved from Melbourne to Bendles at Buderim in Queensland, where she had hoped to further develop the village concept but it did not progress. Despite her ill-health during her last years at Bendle, Walling continued to write prolifically, rewriting manuscripts, corresponding to newspapers on environmental issues, and trying to republish her books. About a quarter of Walling's designs survive and these are held in the State Library of Victoria and in private collections in Tasmania, South Australia, New South Wales and Victoria. Writer-photographer In 1926, Walling began contributing regularly to
