She considers her paintings to be individual portraits of flowers depicting them in a more sculptural form and in a less domestic manner.
Greer looks to methodologies of art history, particularly that of women's art history studies for influences on her practice. The flower, a more recurring subject matter in her recent works, along with still life, reflect a lighter and more aesthetic view of the world.
In recent years, Greer's interests have settled on nature, particularly flora, with peonies being a favourite. She considers these pieces as individual portraits of flowers depicting them in a more sculptural form and in a less domestic manner.
Greer's process of production is multi-layered, where drawing is an integral part. Working in oils, she starts with outlining shapes on a tonal background. After a tonal underpainting is complete, she examines colour and texture. Several layers are added completing the work using many thin layers of glazing giving the piece tremendous depth. With exploring her past, a return to nature and her rural roots in the countryside, Greer hopes this will instil inspiration for future works.
