Dorothy Graham Renton was a Scottish gardener noted for creating Branklyn Garden in Perth with her husband John. She took the Veitch Memorial Medal for her work in 1954 from the Royal Horticultural Society. Branklyn was described as "the finest two acres of private garden in the country". It is owned by the National Trust for Scotland.
