Aloe castilloniae - 1ga
Aloe castilloniae, a diminutive succulent native to southwestern Madagascar, boasts a creeping, vine-like form, with stems sprawling from the base and clustering into dense rosettes. Each rosette comprises triangular, olive-green leaves, reaching lengths of up to 2.4 inches (6 cm) and widths of 0.6 inches (1.5 cm), adorned with red teeth along the edges and scattered red tubercles on both surfaces. These rosettes, numbering 30-40 leaves apiece, aggregate into expansive clusters, up to 1 meter in diameter. During fall and winter, Aloe castilloniae adorns itself with small, orange-red flowers, arranged in lax clusters atop unbranched stalks. Originating from the Plateau Mahafaly near Joffreville in southwestern Madagascar, this species thrives in porous calcareous sandstone cliffs, where it cascades in drooping rosettes, its stems meandering along the ground in sprawling colonies. Altitudinally, it flourishes between 100 to 250 meters above sea level. Cultivation in warm regions, either
