  • Zantedeschia aethiopica (L)Spreng. Calla lily, Arum lily. Half hardy annual. Distribution: South Africa. The genus name commemorates Giovanni Zantedeschi (1773-1846) an Italian physician and botanist. Born in Molina he studied medicine in Verona and Padua. He corresponded with the German botanist, Kurt Sprengel, who named the genus Zantedeschia in his honour in 1826, separating it from Calla, where, as C. aethiopica, it had been previously described by Linnaeus. He had broad interests, including the effect of different parts of the spectrum of light on plant growth, reporting in 1843, that red, orange and yellow light are heliotropically inactive. The botanic museum in Molina is dedicated to his memory. Aethiopica, merely means 'African'. The leaves are used as a warm poultice for headaches in ‘muthi’ medicine. It has become an invasive weed in parts of Australia. It was introduced, as a greenhouse plant, to Europe in the mid-17th century, where the long lasting flowers are popular in flower arranging and for weddings and funerals – a curious combination (Oakeley, 2012). Photographed in the Medicinal Garden of the Royal College of Physicians, London.
