Aloe Vera

Aloe vera has been cultivated for its soothing gel for thousands of years. As a houseplant it wants exactly what most homes fail to give succulents: maximum window and minimum watering. Get that right and it multiplies into a whole first-aid collection via baby "pups."

Care. South- or west-facing window ideally; leaves that flatten and spread pale are begging for more light. Water deeply but only when the pot dries fully — every two to three weeks typically, less in winter. Gritty soil, drainage, and terracotta pots are perfect. Harvest outer leaves for gel by cutting at the base; the yellow latex layer just under the skin is a laxative — rinse it off for skin use.

Watch for: flat spreading leaves (more light) and brown mushy base (rot — reduce water immediately). Toxic to pets if eaten (the latex causes vomiting and diarrhea) — keep away from chewers.
