After her death in 2006, the Finnis Scott Foundation was established to provide supportive funding to artistic, art historical, horticultural or botanical projects.
She mainly collected plant portraits but also some photographs of famous people, including Cedric Morris, Margery Fish, and Vita Sackville-West.
She first went to Waterperry in 1942, aged 18, at which time it was run by Beatrix Havergal, and helped make it a famous horticultural institution.
Among her work as a plant breeder, she developed a cross between an "orange-peel" clematis (C. orientalis and C. tangutica) she named for Bill MacKenzie.
