Watercolour in my Garden Journal – Bockingford 300gsm
“When you take a flower in your hand and really look at it, it’s your world for the moment. I want to give that world to someone else. Most people in the city rush around so, they have no time to look at a flower. I want them to see it whether they want to or not.”
- Georgia O’Keeffe
Zantedeschia is a genus of herbaceous flowering plants in the family Araceae, native to southern Africa from South Africa north to Malawi. The Zantedeschia species are poisonous due to the presence of calcium oxalate. All parts of the plant are toxic, and produce irritation and swelling of the mouth and throat, acute vomiting and diarrhoea. However leaves are sometimes cooked and eaten. Who would believe that these beauties carry a deadly secret?
In the South-West of Western Australia, Z. aethiopica was introduced for horticulture. It has become a widespread and conspicuous weed of watercourses, heath, and wetter pastures.
The so-called white calla is derived from Z. aethiopica. All varieties with flowers with shades of yellow, orange, red, purple are mainly derived from Z. albomaculata, Z. pentlandii and Z. rehmanni.
