From 1944, after both her parents had died, Ashby began to make longer trips to collect plants as specimens for various herbaria and also to propagate from seeds and cuttings. She was an active member of the South Australian branch of the Society for Growing Australian Plants. From 1963 to 1977, she made regular car journeys each year to collect and illustrate plants, driving to Southwest Australia in the winter and to the Australian Alps in the summer. In 1972, she moved to Victor Harbor and died in 1987.[1]
