Madagascar Ocotillo (Alluaudia procera)

Endemic to the semi-arid spiny thickets of southern Madagascar, Alluaudia procera is an architectural deciduous succulent featuring towering silver-grey columns adorned with sharp spines and pairs of rounded, fleshy leaves. It is remarkably drought-adapted, shedding its foliage during prolonged dry periods or cool winters while continuing photosynthetic activity through its bark. Capable of reaching up to 15 meters in habitat, this prehistoric-looking collector's plant adds striking structural drama to succulent displays.
