Nemesia, a member of the snapdragon family, is an annual herb that is widely grown in cultivation as the clusters of colourful flowers make it an attractive garden plant (4). The flowers may be white, cream, pink, mauve or sometimes red, with brown mottling on the throat of the flower. Each flower measures around 20 millimetres across, and has four rounded upper petals, with a large, lower lip and coarse hairs in the mouth. The leaves of nemesia are narrow and lance-shaped, and have slightly toothed edges (2) (4). The fruit of this plant is a dry capsule, which contains the seeds (1).
Endemic to the Cape Floristic Region, an area of remarkable plant diversity in south-western South Africa. Within this region nemesia is distributed from Hopefield south to Melkbos (2).
Nemesia grows on sandy flats, often in sandveld, an area of light sandy soil (2).
Nemesias flower in August, with the attractive blooms lasting just until September (2)
While nemesia is classified as Near Threatened (3), there is no information available at present detailing the specific threats that this species faces. However, the Cape Floristic Region, the area to which nemesia is restricted, is facing threats of urban development, encroaching agriculture, and invasive alien species (5).
There are no known specific conservation measures in place for the nemesia. However, within the Cape Floristic Region there are a number of protected areas (6), and a number of conservation organisations are working to conserve this botanically rich habitat. Conservation actions include purchasing land to protect it from the threats of encroaching agriculture and urban development (7), the removal of alien plants, and the establishment of new protected areas (5). Such measures should hopefully prevent the nemesia from becoming threatened with extinction.
