Euphorbia ammak or the African Candelabra is a fast growing tree-like succulent.
There are two varieties one with pale green stems and a variegated variety with marbled cream-yellow and pale blue-green stems.
The thick, swollen stem and branches have 4 or 5 longitudinal wavy ridges. Along each ridge are evenly spaced pairs of horn-shapes spines.
When conditions are warm and wet small leaves are produced towards the top of each branch.
As with all Euphorbia the flowers are very tiny and undeveloped and found on the tip of each stem.
Euphorbia ammak is an impressive sculptural looking plant but it is will grow very tall, the spines are very sharp and the sap is poisonous and can burn the skin. Wear gloves and eye protection when pruning or moving the plant.
