Euphorbia fortuita (fortuita means "discovered by chance") is known from a small area between Ladismith and Barrydale in the arid Little Karoo.
The plants resemble Euphorbia colliculina from the Oudsthoorn area, but the cyathia are very pubescent and the involucre glands purple instead of greenish-yellow. The peduncles are not persistent, while those of E colliculina are occasionally persistent.
Euphorbia fortuita is grown from seed. The plants prefer full sun and good drainage with a minimum winter temperature of about - 3 degrees Celsius.
