Cactus Euphorbia trigona

Euphorbia trigona — often known as the African Milk Tree — is a striking, architectural succulent that has become increasingly popular for both indoor and outdoor plant collections. With its upright, columnar stems and triangular cross-section, Euphorbia trigona features vertical ridges lined with small, sharp spines and teardrop-shaped leaves emerging along the edges. Its unique, sculptural appearance makes it a standout choice for modern interiors, succulent gardens, and plant lovers seeking bold, easy-care plants.

Euphorbia trigona thrives in bright, indirect light, but it can also handle some direct sun, especially when acclimated gradually. It prefers well-draining cactus soil and benefits from a thorough watering only when the soil is completely dry. Like many succulents, it is highly drought-tolerant, and overwatering can lead to root rot. This plant loves warm temperatures (ideally between 18-26°C) and should be protected from frost, as it is not cold hardy. During the growing season (spring and summer), a light feeding once a month with diluted cactus fertilizer can support healthy growth, but this is not strictly necessary if the plant is already in nutrient-rich soil.

It’s important to note that Euphorbia trigona, like all Euphorbias, contains a milky sap that can be irritating to skin and toxic if ingested. Gloves are recommended when handling or pruning.

Euphorbia trigona is a reliable bestseller thanks to its dramatic form, low maintenance needs, and versatility in both indoor and outdoor displays. It’s an excellent addition to succulent assortments, architectural plant collections, or contemporary plant displays. Its resilience and bold silhouette make it appealing to both beginners and seasoned plant collectors.
