Euphorbia Polygona is a succulent plant from the spurge family (Euphorbiaceae). Originates from South Africa, where it usually grows on completely rocky soils. 

On offer are some of my mother plants, nicely branched, from the succulent collection; fully established and grown over several years from a head cutting in a species-appropriate manner; potted in well-drained, self-mixed organic substrate - specially adapted for euphorbias; repotting only desired in 2-3 years, grows slowly without being heavily fertilised, therefore robust & extremely healthy (100% organic quality over quantity! ); not hardy; forms new side shoots over time, the plant is intended for a bright/(fully) sunny location (avoid waterlogging, please!), Have fun with your new Euphorbia Polygona!

Did you already know?
The botanical name Euphorbia is derived from Euphorbos, a Greek physician from the 1st century AD. Euphorbia dates back to the 18th century. In 1753, the botanist and taxonomist Carl Linnaeus named the entire genus Euphorbia in honour of this physician.
And yes, that's right, euphorbias are not cacti, even though many of them look quite similar to cacti.
