About Triangular euphorbia
Euphorbia triangularis, known as River Euphorbia or Candelabra Euphorbia, is a shrubby succulent native to South Africa that can reach several meters in height. Its upright, branched stems, triangular or quadrangular in cross-section, feature prominent ribs and spines, creating a unique architectural silhouette. It is ideal for xeriscaping gardens, sunny patios, or as a large potted indoor plant, adding an exotic and sculptural touch.
Native range
Southern Africa (especially South Africa, Zimbabwe, and Mozambique)
Care tips
It requires full sun or bright partial shade for optimal growth and healthy coloration. Watering should be moderate in spring and summer, allowing the substrate to dry out completely between waterings, and very scarce or none in winter. Use a well-draining substrate, specifically formulated for cacti and succulents. A common mistake is overwatering, which can lead to root and stem base rot.
