Where it grows
Euphorbia susannae is an extremely range restricted species, and only occurs near the town of Barrydale in the Western Cape, South Africa.
Special features
Euphorbia susannae is an attractive cluster-forming species with light-green, oval stems. The ribs are lined by downwardly protruding tubercles that resemble spines. Produces typical small Euphorbia flowers near the end of summer.
Known as ‘Knoppiesnoors’ in Afrikaans.
Care Guide
These Euphorbia are not fussy plants and reasonably easy to care for. Due to the fact that they originate from the Karoo, they prefer plenty of light and grow well when given either full morning sun or when grown under 40% shade cloth. They need to be kept in a gritty soil to ensure good drainage, as they are prone to root rot if kept wet. They should get plenty of water during the warmer months of the year, but should not get any water during winter, as they are dormant during this time.
Growing season
Spring and summer.
