Description:
E. ingens E.Mey. ex Boiss., is a succulent tree that typically grows up to 12 meters tall and is characterized by its distinctive candelabra-like branching structure. The stems are ribbed and covered with small spines. Like other Euphorbia species, its sap is toxic and can cause skin irritation.

Leaves: Has small, short-lived leaves that appear at the tips of the branches. They are usually lanceolate (spear-shaped) and fall off early.

Flowers: The flowers, known as cyathia, are yellowish-green and appear in clusters at the ends of the branches. Each cyathium consists of a cup-shaped structure containing several male flowers and a single female flower. 

Flowering time: Autumn to winter (April-June)

Fruits: A round 3-lobed capsule, that turns red to purple when ripening.

Origin: South Africa

Habitat: Rocky outcrops or in deep sand within bushveld vegetation. Distributed throughout KwaZulu-Natal, Swaziland, Limpopo Province, Gauteng, North-West Province, Mozambique, Zimbabwe and further into tropical Africa.

Uses: Ornamental Use: Its unique candelabra-like shape and striking appearance make it a popular choice for ornamental planting in gardens and landscapes. It is especially valued in xeriscaping due to its drought tolerance.

Traditional Medicine: In some African cultures, parts of E. ingens are used in traditional medicine. The latex or sap has been used to treat wounds, ulcers, and as a purgative, although caution is needed due to its toxic properties.

Hedge and Barrier: The plant's dense, spiny structure makes it suitable for use as a natural barrier or hedge, providing protection and privacy.

Cultural Significance: In some regions, E. ingens is also used in cultural rituals and as a symbol in various traditional practices.

Propagation: propagated through seeds and cuttings.
