Euphorbia avasmontana: In-Depth Information and Care Instructions
Euphorbia avasmontana, commonly known as the Slender Candelabra Euphorbia, is a captivating succulent native to Namibia and South Africa. Its tall, columnar stems, adorned with paired spines, give it a distinctive, candelabra-like appearance. While it resembles a cactus, it belongs to the Euphorbiaceae family and is known for its unique milky sap.
Main Features of Euphorbia avasmontana:
- Growth Habit: This many-stemmed succulent branches at the base, with individual stems reaching up to 2.5 meters in height and approximately 6-7 centimeters in diameter. The stems are characterized by 5 to 7 ribs with shallow furrows. Over time, it can form expansive clumps nearly as wide as its height.
- Spines: Paired, straight spines measuring 1-2 centimeters in length run along the ribs, connected by a horny margin, creating a striking pattern along the stems.
- Flowers: Produces small yellow cyathia, about 8 millimeters in diameter, arranged in 2–3 cymes between spine pairs. These blooms often appear in spring and autumn but can occur during other months as well.
Natural Habitat
Euphorbia avasmontana is found on both sides of the Orange River, spanning regions in South Africa (Namaqualand and Bushmanland) and Namibia. It thrives on hill slopes and rocky outcrops, occasionally populating hilltops and other terrains. Annual rainfall in its native habitat ranges from 150 to 300 millimeters. It often coexists with species like Aloe dichotoma.
Euphorbia avasmontana: Comprehensive Care Guide
- Light: Prefers full sun to partial shade. Ensure it receives at least 6-8 hours of bright light daily to maintain its health and form.
