Spiny tree (not a palm) from the spiny forest of SW Madagascar with deciduous leaves and white flowers. On the large side for the genus, and probably the second most common Pachypodium in cultivation after P. lamerei, which is a similar looking plant.

Excellent container plant given good drainage, good light, and lots of water in summer. Obeys a seasonal growth cycle with some degree of rest/dormancy in winter, especially in marginal climates. Handle with care during this period (cold sensitive) and provide much less frequent water when the plant is leafless. Relatively late to flower (tall trunk before branching begins).

Easily confused with Pachypodium lamerei, which tends to branch lower, and especially P. mikea, which has very different flowers.
