A prolific and versatile artist, Rosie excels in a variety of disciplines including botanical art, textiles, landscapes and figure drawing. She trained at St Martin's School of Art in London, gaining a first class Honours degree in Art and Design. She won a scholarship to Parsons School of Design in New York and was later awarded a travel scholarship to paint landscapes in Europe.

As a botanical artist, Rosie holds a Royal Horticultural Society (RHS) Gold medal for botanical watercolour portraiture and was elected to the Society of Botanical Artists. She produces a limited number of plant portraits annually, most of which are commissioned or sold privately.

Rosie has worked as a textile artist in fashion, ballet, theatre and interior design. Her clients have included Christian Dior, David Bowie, Sir Anthony Caro, Sir Roland Penrose and Lee Miller, Frederick Gore and Jean Muir. She is currently Visiting Lecturer in drawing and painting at the Academy of Art University, San Francisco, a course leader in a variety of art based subjects in Canada, the US, Europe and Antarctica, tutor for the Field Studies Council GB and founder Vice Chairman and Artistic Director of the South West Society of Botanical Artists.

Lately, Rosie has specialized in painting the disappearing polar landscapes in the Arctic and Antarctic. All work is done in situ, often in extreme conditions.
