Candelabra Cactus Identification Guide

Key Identifying Features

Candelabra Cactus is a common name for several upright, branching Euphorbia species — notably Euphorbia lactea and Euphorbia ingens — whose tall, ribbed, forking stems resemble a many-armed candelabra. Despite the name, these are succulent euphorbias, not true cacti, and the giveaway is the milky white sap.

• Upright, columnar, ribbed stems that branch into candelabra-like arms
• Milky white latex sap when cut (NOT a true cactus)
• Ribs lined with paired short spines and small short-lived leaves
• Green to gray-green stems, sometimes with marbled patterns (E. lactea)

Leaves & Stems

The stems are the showpiece: erect, 3-4+ ribbed (winged) columns that branch upward, forming a candelabra silhouette. Euphorbia lactea often shows an attractive white-and-green marbled stripe down the rib centers. Along the rib margins sit pairs of small, sharp spines (actually modified structures with a stipular origin), and tiny leaves appear briefly near the growing tips then drop. Cutting any stem releases copious milky latex — the single most important ID and safety feature, since true cacti have clear sap and bear spines from areoles, which euphorbias lack.

Flowers & Fruit

Like all euphorbias, the "flowers" are reduced cyathia rather than showy blooms — small and easily overlooked, sometimes yellowish or reddish near the rib edges. They are not the main identifier. Fruit is a small three-lobed capsule. Many ornamental forms (including crested 'Coral Cactus' grafts of E. lactea) are grown for stem form rather than flowers.

How to Tell It Apart from Look-Alikes

• True columnar cacti (Cereus, Pachycereus): have areoles, clear sap, and spines emerging from felted areoles; Candelabra Cactus has milky sap and spines along rib margins without areoles.
• Euphorbia trigona (African Milk Tree): narrower, distinctly triangular stems with leaves along the ridges; Candelabra forms are stouter and more tree-like.
• Saguaro: a true cactus with areoles and clear flesh; never has milky sap.

Where You'll Find It

Native to tropical Africa and India (depending on species), Candelabra Cactus is grown as a dramatic landscape specimen in frost-free climates (USDA zones 10-11) and as a tall architectural houseplant elsewhere. Look for it as a sculptural focal point in succulent gardens and modern interiors.

Quick ID Checklist

• Upright, ribbed, candelabra-branching green stems
• Milky white sap when cut (confirms Euphorbia, not cactus)
• Paired spines along rib margins, no areoles
• Small, quickly-shed leaves near growth tips
• Possible white/green marbled ribs (E. lactea)
• Tree-like, architectural habit

Safety: The milky latex is toxic and a serious skin/eye irritant. Always wear gloves and eye protection when pruning, and keep away from pets and children.
