🌱 Morphology
Semi-succulent and caudiciform tree, with relatively fast growth for the Pachypodium genus. It develops a thick, fleshy, bottle- or spindle-shaped trunk that can reach approximately 60 cm in diameter at the base. Adult specimens can grow several meters tall and develop a branched crown at the top.

The bark is greyish to silvery brown, and the branches are relatively short, thick, and thorny. The spines, approximately 1–1.5 cm long, are associated with leaf scars.

The leaves are concentrated at the ends of the branches. They are simple, narrowly oblong to lanceolate, bright green, with a prominent midrib and a petiole that can reach about 6 cm. The plant is deciduous and may become completely bare during the unfavorable season.

The swollen trunk and roots provide a major reserve of water and nutrients, allowing the plant to survive periods of drought.

🌍 Distribution, habitat, and family
Family Apocynaceae. It is endemic to Madagascar, with a natural distribution mainly in the north and west of the island. It is classified as a semi-succulent tree of the seasonally dry tropical biomes.

It grows in regions with pronounced seasonal rainfall and is part of Madagascar's xerophytic flora. Known populations include areas in the Befandriana-Nord region, where several-meter-tall tree specimens have been recorded.

The name Pachypodium comes from the Greek pachys, thick, and podos, foot, referring to the characteristic swollen bases and stems of the genus.

❄️ Temperature
USDA Zone 10a Tolerates minimum temperatures of up to −1 ºC, as a general guideline for acclimated plants kept dry.

It is a frost-sensitive species. The Missouri Botanical Garden recommends growing it in USDA Zones 10–11 and specifically notes its intolerance to cold and frost. During winter, it should be protected and kept with very dry potting mix.

The combination of low temperatures and moisture in the root system increases the risk of damage and rot.

☀️ Lighting
Approximate DLI PAR: 20–30 mol·m⁻²·day⁻¹.

It requires very high light levels and grows best with direct sun or extremely intense light. Insufficient light promotes leggy growth and makes it difficult to develop a compact structure.

Specimens from greenhouses must be gradually acclimated to direct sun. In summer, it can be grown outdoors provided there is good air circulation and excellent drainage.

💧 Growth cycle and watering
Winter dormancy. It is a species from a seasonally dry tropical climate, adapted to alternate periods of growth with dry phases. During the active phase, it develops leaves and new shoots, while during the unfavorable season, it gradually loses its foliage and uses the reserves stored in the trunk and roots.

During active growth, it is recommended to water thoroughly and let the potting mix dry out completelybefore watering again. It should not be kept permanently moist.

When the leaves begin to fall, watering should be gradually reduced. Once it has completely shed its leaves and temperatures are low, it should be kept almost dry.

The complete loss of leaves is part of its natural strategy for coping with the unfavorable season and does not necessarily indicate a physiological problem.

🌸 Flowering
The flowers are large and very striking for a Pachypodium, approximately 7 cm in diameter, with a white corolla and yellow center. They are fragrant and resemble Plumeria flowers in appearance.

One particularly interesting feature is that it can flower when the plant is completely bare. The flowers appear in compact terminal inflorescences, with approximately 3–30 flowers. Kew botanical records expressly document leafless specimens at the time of flowering.

Natural flowering occurs mainly during the Southern Hemisphere winter, although when grown in Spain, it may occur at a different time depending on the temperature, dormancy period, and lighting conditions.

🌿 Nutrition
During the active growth period, Desert CHOICE® Succulents is recommended, applied after watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering.

Fertilizing is not recommended during dormancy or while the plant is leafless and showing reduced activity.

This is an inimitable xerophyte grown in Madrid in a high-tech square pot with a substrate enriched with mycorrhizal fungi and biofungicides.
