Euphorbia ambarivatoensis

A rare succulent spurge endemic to rocky ground in the far north of Madagascar, near Antsiranana. Little is published about it, so care follows the measured hot, seasonally dry climate and what works for other northern Malagasy rock euphorbias: strong light, constant warmth, and a dry rest in the cooler months.
