Gilbert Dashorst graduated from the North Adelaide School of Art in 1980 before travelling to Europe as a freelance illustrator for two and a half  years.  Returning to Adelaide in 1983, he started as the botanical illustrator for the Botanical Gardens of Adelaide and the State Herbarium, illustrating plant material for scientific publications world-wide; a position he held for almost 30 years, leaving in mid 2012.

In 1988, a Churchill Fellowship enabled Gilbert to spend 5 months working with botanists and botanical artists in Leiden (the Netherlands) and one month at Kew (England) enhancing his botanical illustration skills and research into Australian botanical artists.

In 1990, Gilbert produced the book “Plants of the Adelaide Plains and Hills” in conjunction with John Jessop, which is now in its third edition.

During the period 1986-1994, Gilbert taught scientific illustration at TAFE and also gave sessions to botany students at the University of Adelaide.  He also visits schools to explain the role and art of botanical artists.
