Pachypodium Lamerei

The Pachypodium Lamerei, often nicknamed the Madagascar palm, is a plant as fascinating as it is exotic. Although it resembles a palm tree with its slender trunk and crown of leaves, it is actually a succulent plant from the Apocynaceae family.

Native to southern Madagascar, the Pachypodium Lamerei develops a thick, silvery trunk covered with long, sharp spines that serve as protection as well as a water reservoir. At the top of this trunk grow narrow, glossy green leaves arranged in a rosette, recalling the silhouette of a tropical palm.

Highly appreciated as a decorative indoor plant, Pachypodium can reach up to 2 meters in height in a pot and more than 5 meters in its natural environment. Its graphic silhouette, ease of care, and drought resistance make it a must-have for lovers of low-maintenance and original plants.

The Pachypodium lamerei is endemic to the dry regions of southern Madagascar, where it grows on rocky, well-draining soils, exposed to full sun most of the year.

To grow well, this shrubby cactus needs a very bright exposure:

🌞 Direct sunlight: minimum 6 hours per day.

🌤️ Indoors: place near a south- or west-facing window.

🚫 Warning: lack of light will slow growth, cause leaf drop, and may lead to deformation.

The Pachypodium lamerei has an excellent ability to store water in its trunk:

🌱 Spring / summer: water once every 10 to 15 days, only when the substrate is completely dry.

🍂 Autumn / winter: greatly reduce or completely stop watering during dormancy.

⚡ Golden rule: better too little water than too much. Excess moisture can cause irreversible trunk rot.

🌞 Ideal temperature: between 20°C and 30°C.

❄️ Minimum temperature: 10°C. Frost is fatal to the plant.

🏠 Advice: bring it indoors as soon as autumn arrives if grown outdoors.

The Pachypodium Lamerei fears excess water, so it is crucial to provide a very well-draining soil:

🪴 Ideal mix: cactus potting soil + 50% pumice or pozzolana.

🌱 Drainage: use a pot with drainage holes and add a drainage layer at the bottom.

The flowering of the Pachypodium lamerei is rare but spectacular:

🌸 Season: usually in midsummer, after several years of cultivation.

🎨 Color: white flowers with a yellow center, star-shaped.

🕑 Duration: only a few days.

💡 Flowers appear only on mature, well-rooted plants exposed to strong light and having benefited from a winter rest period.

FAQ - Pachypodium Lamerei

How to recognize excess moisture in a Pachypodium Lamerei?

Excess moisture appears as softening of the trunk, yellowing followed by leaf drop, and sometimes a musty smell at root level. If this occurs, immediately reduce watering and check drainage.

How to know if my Pachypodium Lamerei lacks water?

Lack of water causes progressive wilting of the leaves, or even their drop. The trunk may also wrinkle slightly. This indicates that the plant is using its reserves. Moderate watering is enough to correct the problem.

Can my Pachypodium Lamerei live outdoors?

Yes, but only in summer. It appreciates heat and direct light. However, as soon as temperatures drop below 10°C, it must be brought indoors to avoid any risk of frost.

What is the best time to repot Pachypodium Lamerei?

Repotting is ideally done in spring, every 2 to 3 years, in a slightly larger pot. Use well-draining cactus soil, enriched with pumice or pozzolana.

My Pachypodium Lamerei has no more leaves in winter, is this normal?

Yes, this is a normal dormant phase. Pachypodium often loses its leaves in winter. Reduce watering and wait for spring for new growth.
