Augusta was the daughter of a Gloucestershire vicar, chaplain to the Prince Regent. She lived in London all her life and was married to Theodore Gibson Withers, an accountant, who was 20 years her senior. They were married on 23 July 1822 in Marylebone.[2]
John Claudius Loudon commented in the 1831 Gardener's Magazine that her talents were of the highest order, and that "to be able to draw flowers botanically, and fruit horticulturally, that is, with the characteristics by which varieties and subvarieties are distinguished, is one of the most useful accomplishments of your ladies of leisure, living in the country."[5]
In 1815, in an attempt to clarify the nomenclature of cultivated fruit varieties and reduce the number of synonyms in common use, William Jackson Hooker initiated a project of fruit drawings in watercolour stretching over 10 volumes. Suffering a stroke in 1820, Hooker was unable to finish the work. Four other artists, including Augusta Innes Withers and Barbara Cotton were commissioned to complete the work,[6] ironic since Withers had been refused a position as a botanical artist by Hooker's son, Joseph Dalton Hooker.[7]
Withers painted the 12 colour plates for Robert Thompson's The gardener's assistant.[8]
