Othonna herreiOriginally from Cape Province, Namaqualand, Richtersveld, South Africa. Habitat and Ecology: Succulent Karoo. Othonna herrei is not generally plentiful at any locality and populations are widely and thinly scattered only on very rocky slopes in remote inaccessible areas. The older mature plants produce little new growth, few flowers and little fertile seed. The younger plants produce the most flowers and seed, but flowering is still rather limited in comparison with other othonna species. This species is popular in cultivation, and is potentially threatened by collectors removing mature individuals from the wild, for sale in the specialist succulent trade.
