Aloe — 53 species

Aloe is a succulent genus native to Africa and the Arabian Peninsula, prized for its fleshy, water-storing rosettes. Bright indirect light for six to eight hours daily suits most species — direct harsh midday sun can scorch leaves — and a south- or west-facing window works well indoors. Water deeply but infrequently, roughly every two to three weeks in the growing season and less in winter, allowing soil to dry out completely between waterings to prevent root rot. All Aloe species are toxic to cats and dogs: saponins and anthraquinones (aloin) cause vomiting, lethargy, and reddened urine. Keep out of reach of pets.
