Blounoorsdoring

Species Card Details

Importance:

The blounoorsdoring , blue euphorbia in English, is a drought-tolerant succulent valued in ornamental horticulture for water wise gardens. Its stems can be used as emergency livestock fodder after the latex has dried to reduce toxicity. The species itself is not currently threatened, but many southern African Euphorbia species face pressure from illegal collection and habitat loss, underscoring the importance of ecological research and conservation planning.
