Growth context and background of Euphorbia fiherenensis


This species is native to the Fiherenana River region in southwestern Madagascar, a dry, sun-baked area with well-draining, sandy soils and low humidity. Temperatures range between 10–28 °C year-round, with long dry spells and occasional brief rainfall. Euphorbia fiherenensis evolved to handle full sun and infrequent watering. Indoors, it maintains a slim profile and rarely branches, making it perfect for modern, minimalist spaces. Its sap is toxic and can irritate skin, so gloves should always be used when handling or pruning. Keep out of reach of pets and children.
