Botanical Illustration Certificate Program

Designed to provide a certificate of competence in the classical approaches and disciplines of botanical illustration, this program teaches you to draw and paint plants in a technically detailed manner.   Drawing on the Garden’s mission to engage people with the natural world, our courses emphasize proper set-up of live specimens, accurate drawing, correct depiction of tone and value, and work in the traditional media of pencil, pen and ink and watercolor.
