“Rooibos is not only a fascinating medicinal plant, but also a beautiful shrub,” says Suellen Perold, who recently received a Certificate in Botanical Art and Illustration from Wellesley College in the USA (www.wellesley.edu).

She also entered the Kirstenbosch Biennale 2013 competition with an illustration of Rooibos as one of the entries (illustration attached). Her illustrations of medicinal plants will be part of a show of botanical art, on view at Kirstenbosch, Cape Town from 30 August to 15 September 2013.
