Gasteria langebergensis (Van Jaarsv.) Van Jaarsv. & Zonn. 

🌱 Morphology
Small acaulescent Gasteria, compact and slow-growing, initially solitary but capable of multiplying from the base to form groups of 5–10 heads, measuring about 9–15 cm tall and up to 18–24 cm in diameter. Each rosette has 8–12 leaves arranged in two opposite rows (distichous), narrow, linear-lanceolate, approximately 8–12 × 2.2–2.7 cm, ascending and then spreading.

The leaf surface is matte, grey-green, densely speckled with small white spots that form indistinct transverse bands. It feels slightly rough to the touch (asperulose), a characteristic that helps distinguish it from some closely related species. During the summer drought, the leaves may take on reddish tones and the upper surface becomes channeled. The margins are wavy and provided with tiny whitish teeth; the apex is acute, sometimes acuminate, with a small rigid tip slightly off-center.

🌍 Distribution, habitat and family
Family Asphodelaceae, tribe Alooideae, section Longiflorae, series Multifariae, genus Gasteria. Although originally described as Gasteria disticha var. langebergensis, it is now recognized as a separate species.

It is endemic to the Western Cape, South Africa, and its known range is concentrated between Worcester and Robertson, on the lower southern slopes of the Langeberg. It grows on rocky outcrops, mainly on schists and dolomites, within the Breede Shale Renosterveld and Succulent Karoo vegetation, protected under nurse shrubs that provide shade and protection from the intense summer heat.

It is an extremely restricted species: the SANBI assessment indicates a very small range and two known localities, with habitat loss associated with limestone extraction in one of them.

❄️ Temperature — USDA 9
It tolerates minimum temperatures of up to −7 ºC. However, when grown as a houseplant, it should be protected from severe frosts accompanied by persistent moisture.

☀️ Lighting
Shade–partial shade. In nature, it grows protected by shrubs, and SANBI recommends protecting it from intense direct sunlight. Approximate DLI: 10–20 mol/m²/day.

💧 Growth cycle and watering
Summer dormancy. It is adapted to a regime with winter rains and pronounced summer drought. The leaves regain their maximum turgidity after the winter rains and serve as a reserve to get through the long dry period. It is recommended to water during the cool growing season, allowing the substrate to dry out partially, and to greatly reduce watering during the summer.

🌸 Flowering
Flowering occurs in the southern winter, mainly from June to July, approximately equivalent to December–January in Madrid. The inflorescence is extraordinarily long for the size of the plant, reaching 65–84 cm, and usually rests on the branches of the nurse shrub. The raceme, measuring about 39–41 cm, can bear 28–34 flowers, although up to eight may be open at the same time. The flowers measure about 20 mm, are pendulous, with a swollen base, orange-pink on the lower half and white with green streaks on the upper half. They are mainly pollinated by nectar-feeding birds.

🌿 Nutrition
During the active growing season, Desert CHOICE® Aloes, Haworthias & Co. is recommended, with a high content of potassium and bioavailable calcium. Apply with watering, reducing or suspending fertilization during summer dormancy.
