Product Description:

These are very well established plants.

Beefy- and looking mean as hell!... Euphorbia grandicornis is a striking, sculptural succulent with thick, three‑angled stems edged in prominent paired spines that curve outward like bull or rhino horns. The stems are bright green, heavily ridged, and form an irregular, branching structure that gives the plant a dramatic, architectural presence. Small yellow cyathia (the euphorbia flower form) appear along the ridges in warm seasons. Its bold silhouette and horned spines make it a standout specimen in arid collections and container displays.

Growing Conditions:

Grow in bright light with several hours of direct sun. Use a fast‑draining cactus or mineral‑rich mix. Water sparingly, allowing soil to dry thoroughly between waterings. Protect from frost and avoid cold, wet conditions. Provide airflow and avoid overpotting to reduce rot risk. Excellent as a sculptural container plant indoors or outdoors in warm climates.

Ships in 3.5" pots. You will receive a plant similar to the ones pictured, though size and fullness may vary. Please understand that shipped plants have bumpy rides. A few broken leaves or small stems are normal during shipping and are not considered damage. Broken stems can be rooted once the cut end dries to start new growth. Plants may arrive semi‑dormant, and in winter they may naturally drop a few leaves. If your plant arrives rotting or dead, we will replace it. Please contact us with photo proof within 24 hours of delivery. After 24 hours, plant care becomes the buyer’s responsibility, though we’re always happy to answer questions and help you succeed. We also add brief instructions on getting started when you open your box. We want our plant babies to have happy new homes! 🥰
