Ginger studied at Kingston Art School (1932-5) and at Central School of Arts and Crafts (1936 (part-time), 1937-9). She had already committed herself to illustration before joining Central. Ginger contributed nineteen water colours to 'Recording Britain' and, in 1941, began an artist/author partnership with Mrs Robert Henrey that lasted some thirty years. In 1943 Ginger wrote and illustrated Alexander the Circus Pony for Puffin Picture Books.
Her style was in the tradition of British topographical water colours, pale washes overlaying meticulous detail. In her School Print her colour was seen as possibly too pale for the purpose. She had left London during the Second World War for Keynsham, and it has been suggested that her print is of Bristol, nearby.
