Seaweed is a talking point these days as a potential and as yet untapped source of biofuel and food - but less so as a subject for artists. The upcoming New Zealand Festival of Nature in Otepoti Dunedin includes a workshop in Marine Botanical illustration focusing on drawing and painting seaweed found in the Otago Harbour and environs. Artist and tutor Wayne Everson has taught numerous courses including Botanical Art and Illustration for The Garden School of Art in Dunedin since 2015. The seaweed images in the gallery are from students who attended one of the courses. Lynn caught up with Wayne who says the Marine Botanical workshop is something new for him.
