The botanical watercolours featured were painted between 1894 and 1949 by artists James and Charles de Alwis and Jean Kinloch Smith. These artworks are part of the Gardens’ archives which include more than 2,000 botanical paintings, as well as hundreds of sketches, line drawings and photographs. Since March 2021, a selection of the best and most representative artworks in the Gardens’ collections have been on display in the newly opened Botanical Art Gallery. Located within the Gallop Extension, the gallery is one of the Gardens’ two black and white houses designed by British architect Regent Alfred John Bidwell.
