Deirdre is a recognized botanical artist who exhibits locally and internationally. She paints in watercolour on paper and vellum. The paintings take many hours and are always botanically correct. She has paintings in public collections at the Royal Botanic Gardens, Kew, London, the Hunt Institute of Botanical Documentation, Pittsburgh, USA, and in the Florilegium collection at the Royal Botanic Gardens Sydney. She won a gold medal at the Royal Horticultural Society in London for her series of eight Syzygium species in 2006, and Silver-gilt medals for her series of Australian mangroves in 2012 and 2015. Her work was highly commended in the Waterhouse Prize for Natural History at the South Australian Museum, Adelaide in 2011, and selected for the 2012 exhibition.

Deirdre was commissioned by Australia Post in 2013 to paint the flowering shrubs of Christmas Island, a region where the plant life is unique because of its geographical location.

In 2013 and 2014 Deirdre travelled to Gallipoli with a group of artists working on a project called ‘Your Friend the Enemy’.  Her paintings were included in exhibitions in NSW, Canberra and Wellington NZ to commemorate the 100 year anniversary of the Gallipoli landings.

In April 2015 Deirdre’s painting Papaver rhoeas (common poppy) won the inaugural Executive Director’s Prize at Botanica. The painting  is now part of the permanent collection of the Royal Botanic Gardens, Sydney.

Deirdre is a PhD candidate in Natural History Illustration at the University of Newcastle. Her research title is ‘Australia’s mangroves: a plant community facing an uncertain future’.
