Aloe juvenna (Tiger Tooth Aloe)


Scientific Name

Aloe juvenna Brandham & S. Carter

Common Names

Tiger Tooth Aloe

Scientific Classification

Family: Asphodelaceae
Subfamily: Asphodeloideae
Tribe: Aloeae
Genus: Aloe


This species is native to Kenya, restricted to a small area near the border with Tanzania.


Aloe juvenna is a popular branched succulent with thin, erect to arching stems, densely packed with fleshy, triangular leaves, and tipped with a small, tight rosette. It branches from the base to form clumps of stems, each up to 2 feet (60 cm) long. Leaves are green with reddish to brown tones in full sun and prominent creamy-white spots. They have marginal teeth that merely look sharp, hence its common name "Tiger Tooth Aloe." Flowers are red to orange-red with a yellow-green mouth and appear in summer on a usually unbranched, up to 10 inches (25 cm) tall spike.

The specific epithet "juvenna" is a pseudo-Latin word from English "juvenile." In 1979 someone misread the original label of a plant tagged as "possible juvenile Aloe," and it was labeled "juvenna." That label eventually became its official name.

How to Grow and Care for Aloe juvenna

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 juvenna can withstand temperatures as low as 20 to 50 °F (-6.7 to 10 °C), USDA hardiness zones 9a 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.
