The Euphorbia ampliphylla is a striking succulent tree known for its impressive height and architectural form. It is often planted as an ornamental tree or as a natural barrier due to its thick, spiny branches. Unlike smaller, shrubby species, this one can dominate landscapes with its towering, segmented branches.
Native to eastern Africa, particularly found in Ethiopia and surrounding regions, the Euphorbia ampliphylla is a large, tree-like succulent that can grow up to 30 feet tall. Its thick, green, columnar stems are ribbed and bear spines along the edges, giving it a cactus-like appearance.
The Euphorbia plant produces small, yellowish-green flowers that emerge from the tips of the stems.
These flowers are not particularly showy but play a crucial role in attracting pollinators, especially bees and other insects.
When it comes to care, the Euphorbia ampliphylla thrives in full sun to bright indirect light.
Outdoors, it should be placed in an area with plenty of direct sunlight, while indoors, a south-facing window is ideal.
It does well in typical household temperatures but should be kept in a warm environment above 50°F.
Like most drought-tolerant plants, it requires infrequent watering. Water deeply but allow the soil to dry completely between waterings to prevent root rot.
It prefers a well-drained, specialized succulent soil, sandy, or rocky soil. Adding perlite or pumice can improve drainage. A diluted succulent fertilizer can be applied once a year during the growing season in the spring.
It is best suited for USDA zones 10-12, where temperatures remain warm year-round.
It is not frost-tolerant and should be brought indoors if temperatures drop below freezing.
Euphorbia ampliphylla can be propagated through stem cuttings, though caution is required due to its toxic sap.
Cuttings should be left to callous for a few days before planting in well-draining soil. Propagation from seeds is also possible but less common due to the slow growth rate.
Final Thoughts
Overall, the Euphorbia ampliphylla is a fascinating and dramatic succulent tree that adds height and structure to xeriscapes, desert gardens, or indoor collections. Its resilience, low-maintenance nature, and unique appearance make it a desirable choice for enthusiasts who appreciate bold, sculptural plants. With proper care, this striking Euphorbia can become a long-lived and rewarding addition to any arid plant collection.
