Pachypodium lamerei, commonly called the Madagascar palm, is a succulent shrub or small tree endemic to the dry, spiny thickets of southern Madagascar. Despite its name, it is not a true palm; instead, it forms a thick, spiny, water-storing trunk (caudex) crowned by a rosette of glossy, strap-like leaves. Mature plants can reach 4–6 m outdoors, but typically grow 1–2 m in containers. The trunk is armored with sharp, paired or tripled spines that deter herbivores and reduce transpiration. In ideal conditions and with age, plants produce showy, fragrant white flowers at the branch tips, though flowering is uncommon indoors. It prefers high light, heat, and excellent drainage, growing during warm months and entering a semi-dormant state in cooler seasons. Growth is relatively slow; branching often occurs when the main stem is damaged or after flowering. Its dramatic silhouette, drought tolerance, and architectural presence make it a prized specimen for arid gardens and bright indoor spaces, provided one avoids cold and overwatering.

How to care for Madagascar palm
Water
Water deeply during warm, active growth, then allow the soil to dry completely before watering again. In hot, bright conditions this may be weekly; in cooler or lower light, extend intervals. Keep almost dry in winter; if kept below 15°C/59°F, water sparingly every 3–4 weeks just to prevent excessive stem wrinkling. Always use a pot with excellent drainage, never leave the plant standing in a saucer of water, and avoid pooling water in the crown.
Light
Provide very bright light to full sun. Outdoors, 6–10 hours of direct sun is ideal; indoors, place at a unobstructed south- or west-facing window, or supplement with strong grow lights. Acclimate gradually to intense sun to prevent scorch. Insufficient light leads to lanky growth and leaf drop. Ensure good air movement in high heat to reduce the risk of rot and pests.
Nutrients
Feed only in the active growing season (spring through late summer). Use a dilute, low-nitrogen cactus/succulent fertilizer (e.g., balanced or slightly higher potassium, at 1/4–1/2 strength) every 4–6 weeks. Ensure micronutrients, especially magnesium and calcium, are available, and flush the soil with plain water occasionally to prevent salt buildup. Do not fertilize in winter dormancy or when temperatures are cool and growth has paused.
Temperature
Best growth occurs between 18–32°C (65–90°F) with good airflow. Protect from cold: extended exposure below 10–12°C (50–54°F) risks root damage, and frost is lethal. Short dips to around 5°C (41°F) may be tolerated only if the plant is completely dry. Outdoors, it thrives in hot, arid climates; indoors, keep away from cold drafts and resume heavier watering only when temperatures and growth pick up in spring.
