Aloe juvenna Brandham & S.Carter
Tiger Tooth Aloe
Aloe juvenna, commonly known as tiger tooth aloe, is one of the most widely cultivated compact species in the world for its unique ornamental appearance: rosettes of bright green leaves with white spots and prominent white teeth that give a feline-tooth appearance. Native to the Kenyan highlands, it grows on rocky slopes where its trailing stems form cascading colonies. It is very popular as a hanging plant or in rock gardens.

Origin & Habitat
Morphology
Triangular-lanceolate, bright green with longitudinal white spots, 5–10 cm long. Margins with very showy robust white triangular teeth, up to 4–5 mm long.
ecoTrailing or hanging stems 20–50 cm long, producing terminal rosettes and branching to form dense colonies. Stems become semi-woody with age.
ecoTubular, orange-red, 2–2.5 cm, grouped in compact cylindrical racemes on 25–35 cm peduncles. Blooms mainly in spring.
ecoFibrous and shallow, but with high capacity to adhere to rocky substrates. Root nodes at the joints of trailing stems facilitate rapid rooting.

Propagation Strategy
- 1 Cut an 8–15 cm stem segment with at least one developed rosette.
- 2 Allow the cut to dry in the air for 1–2 days.
- 3 Insert in moist sandy substrate and place under bright indirect light; roots in 2–3 weeks.
- 1 Remove lateral rosettes with already formed roots.
- 2 Callous for 24 hours in the air.
- 3 Plant individually in well-draining substrate.
Perfect for hanging baskets where trailing stems hang decoratively.
Overwatering causing stem and root rot.
Every 2 years; grows quickly and fills substrate easily
Twice a year (spring and summer) with succulent fertilizer diluted to 50%

"Aloe juvenna is frequently confused with Aloe brevifolia, but is distinguished by its pronounced trailing stems and more robust, whiter leaf teeth. Its Kenyan origin makes it more humidity-tolerant than other Horn of Africa aloes."
