A watercolour of Stapelia hirsuta by the little-known Dutch artist Nicolaas Juweel (c. 1639–1704) made a brief public appearance in 1998 at The European Fine Art Fair, Maastricht. Its provenance is uncertain, but it is suggested that the drawing was commissioned by Agnes Block, art collector and owner of a large plant collection, on her estate Vijverhof near Utrecht between 1675 and 1697. It is currently in a private collection in Germany.
