Notes:

Pachypodium densiflorum, also known as the Siby Queen, is a rare succulent shrub native to the granite-rich highlands of Madagascar. Characterized by its bulbous trunk, armored with short spines and topped with deep green foliage, it presents an exotic, prehistoric silhouette. In spring, it rewards growers with clusters of brilliant yellow to orange blooms. Like other caudiciforms, it thrives in sunny, warm, and well-drained conditions, making it an excellent choice for collectors of unusual succulents. Dormant in winter, it requires minimal care—just bright light, gritty soil, and controlled watering. Handle with care; sap may be mildly toxic.
