The Karoo is well known for its many different succulent species. Driving through some parts of the Karoo, specially around the Jansenville area, one will find a variety of euphorbia plants. One in particular stands out. The local euphorbia are smallish, thorny plants with a milky sap and are known as noors, giving the region its name of Noorsveld.
It is uncertain where the word noors comes from. The plant with its yellow flowers reminded the British of gorse and it is thought the gorse was evolved to noors by the Dutch settlers settling in the area.
