Pot Size: 2.5"
Accepted Scientific Name: Browningia hertlingiana
Origin and Habitat:
Browningia hertlingiana is native to the dry valleys and rocky slopes of southern Peru, particularly within the departments of Ayacucho and Arequipa. It thrives in arid, high-altitude regions between 1,500 and 2,500 meters above sea level, where the climate is characterized by intense sunlight, minimal rainfall, and significant temperature variation between day and night. The soils are sandy or stony, offering excellent drainage and minimal organic matter. This cactus is adapted to survive in extreme conditions, storing water in its thick, columnar stems to endure prolonged droughts.
Description:
Browningia hertlingiana is a striking, columnar cactus that can reach heights of up to 10–13 feet (3–4 m) in its natural habitat but typically grows much smaller in cultivation. The cylindrical, blue-green stems feature 8–10 pronounced ribs lined with evenly spaced areoles that bear clusters of brownish-black spines. Younger growth often shows a beautiful glaucous-blue sheen. Mature plants produce tubular, nocturnal white flowers with pinkish outer segments, emerging near the top of the stems, usually in summer. These are followed by small, fleshy fruits.
Cultivation:
Zone: 9–11
Temperature: Prefers warm temperatures between 15–30°C; protect from frost below 5°C.
Growth Rate: Slow to moderate under ideal conditions.
Soil: Use a mineral-based, well-draining mix with pumice and coarse grit to prevent root rot.
Watering: Water deeply but infrequently during the growing season, allowing soil to dry completely between waterings; keep nearly dry in winter.
Fertilizing: Apply a low-nitrogen cactus fertilizer every 2–3 weeks during active growth.
Light: Requires full sun to maintain compact, upright growth and rich coloration. Provide bright indoor light if grown inside.
Pests and Diseases: May be affected by mealybugs or scale; root rot can occur in poor-draining soil or excessive moisture.
Propagation:
Usually propagated from seeds sown in a well-drained, sandy medium. Germination occurs in warm, bright conditions. Stem cuttings are possible but less common due to slow rooting.
