Madagascar Palm is a succulent rather than a true palm. It develops a thick, swollen caudex that forms its trunk, with sharp spines along the surface. A crown of dark green leaves grows at the top. Its dramatic upright shape suits a bright floor position, but it needs careful handling, strong direct light, and room to reach a substantial indoor height.

Light requirements
Madagascar Palm needs bright, direct light at 250 to 1000 μmol·m⁻²·s⁻¹ and at least 6+ hours of direct sunlight each day.
Place it within 2 ft / 60 cm of a south or southwest-facing window.
Give the plant an unobstructed view of the sky for maximum light.
Consider grow lights during wintertime when daylight hours are shorter. Too little light can weaken or stretch growth.
A PAR meter or PAR meter app can measure photosynthetically active radiation as PPFD (μmol·m⁻²·s⁻¹).
Watering
Allow Madagascar Palm soil to dry completely before watering. Check several depths with a knitting needle or chopstick, since the surface may dry before the center. Water considerably less during winter when the plant is not actively growing.
Use room temperature rainwater, distilled water, or reverse osmosis water.
When the mix is fully dry, water thoroughly until liquid exits the drainage holes. Let all excess drain before returning the pot to a saucer or decorative planter.
A container with drainage holes is essential. Wet soil around the succulent roots can quickly lead to root rot.
Very long dry periods may cause leaf loss or crispy edges, but frequent watering is the greater risk.
Soil
Use an organic succulent potting mix with fast drainage. Madagascar Palm stores water in its thick trunk, so dense soil that stays damp can damage the roots.
Make a DIY mix from 2 parts coir, 2 parts coarse sand, and 1 part pumice.
Pot it in a container with clear drainage holes.
Feeding
Feed Madagascar Palm with an organic succulent fertiliser every 2 to 4 weeks from March to October. Use the strength directed on the label. Do not apply extra fertiliser or continue routine feeding during winter dormancy.
Temperature & humidity
Madagascar Palm prefers temperatures from 65 to 86 °F / 18 to 30 °C. Its ideal humidity is 40%. Warm, relatively dry indoor conditions suit its succulent growth better than cool rooms or persistently humid air.
What to expect
Madagascar Palm takes 8 to 10 years to mature, so its indoor growth is slow. It can eventually reach 6 ft / 1.8 m tall. Its mature spread remains much narrower at 1 to 2 ft / 0.3 to 0.6 m.
Varieties & cultivars
P. lamerei ‘Ramosum’: This dwarf cultivar has a compact growth habit and a more rounded corolla lobe.
P. lamerei ‘Variegatum’: Creamy white variegation contrasts with the green leaves.
