Aloe rauhii Reynolds
Endemic to Madagascar.
Aloe rauhii is a small succulent with rosettes of leaves that have white oval spots and tiny white marginal teeth. It produces offsets around its base and creates mounding clumps. The rosettes grow up to 4 inches (10 cm) tall and up to 8 inches (20 cm) in diameter. Leaves are triangular, up to 4 inches (10 cm) long, and up to 0.8 inches (2 cm) wide. They are flushed with violet or bronze when exposed to bright sunlight. Flowers are rose-scarlet, tubular, up to 1 inch (2.5 cm) long. They usually appear in winter or spring on simple or rarely branched, up to 12 inches (30 cm) tall flower stalk.
The specific epithet "rauhii" honors the professor Werner Rauh (1913–2000). He was a professor of Botany at the University of Heidelberg in Germany and Director of the Heidelberger Botanical Gardens.
How to Grow and Care
Light: When growing Aloes indoors, place your plants near a southern or southwest-facing window that gets plenty of bright, indirect light. Outdoors, provide light shade, especially during the hottest parts of the day.
Soil: Plant Aloes in a well-drained soil specially formulated for cacti and other succulents or make your soil mix. Drainage is essential because too much moisture around roots can cause root rot.
Hardiness: Aloe rauhii can tolerate temperatures as low as 30 to 50 °F (-1.1 to 10 °C), USDA hardiness zones 10a to 11b.
Watering: These succulents do need regular watering but are very tolerant of drought conditions for short periods. Water deeply, but only when the soil is dry. Cut back on watering during the winter months.
Fertilizing: Aloes generally do not require fertilizer but may benefit from the extra nutrients.
Repotting: These plants are not particularly fast-growing and will only rarely need repotting. Repot them in the spring in a container a few inches larger in diameter every few years to keep it from becoming rootbound.
Propagation: Propagating Aloe can be done by using the offsets, cuttings, or seeds from a mature plant.
Toxicity: Aloe rauhii is not listed as toxic for people and pets.
