Accepted Scientific Name:
Pachypodium lamerei
Origin and Habitat:
Pachypodium lamerei, commonly known as the Madagascar Palm (though not a true palm), is native to the arid, rocky regions of southern Madagascar. It thrives in dry deciduous forests and scrublands, growing on exposed slopes and well-drained limestone outcrops. In its natural habitat, the plant endures extreme heat, intense sunlight, and seasonal drought. Its thick, spiny trunk stores water, allowing it to survive prolonged dry periods. This drought-adapted succulent tree is well-suited to Madagascar’s harsh climate and nutrient-poor soils.
Description:
Pachypodium lamerei is a striking, trunk-forming succulent that can reach 4–6 feet (48–72 inches) in height when grown in containers, and up to 15 feet tall in the ground under ideal conditions. Its thick, gray-green trunk is covered in sharp, silver spines up to 2 inches long. Narrow, lance-shaped, glossy green leaves grow in a rosette at the top of the trunk, resembling a palm. During the warm season, mature specimens may produce large, fragrant white flowers with yellow centers, which emerge near the crown and contrast beautifully with the foliage.
Cultivation:
Zone: Suitable for USDA Zones 10–12; grow in pots in cooler regions.
Temperature: Prefers 20–35°C; protect from temperatures below 10°C.
Growth Rate: Moderate to fast in warm, sunny conditions.
Soil: Requires a well-draining mix with pumice to avoid root rot and mimic native rocky soils.
Watering: Water thoroughly during the growing season, allowing soil to dry between waterings. Reduce watering in winter.
Fertilizing: Feed every 2–3 weeks with a diluted, balanced fertilizer during active growth.
Light: Requires full sun for best growth; insufficient light may cause leaf drop or weak growth.
Pests and Diseases: Generally pest-resistant but may attract spider mites or mealybugs indoors. Susceptible to root rot if overwatered.
Propagation:
Typically propagated from seed. Sow in a well-draining pumice-based mix, keep warm and lightly moist until germination. Cuttings are rarely successful.
