🌱 Morphology
  Purple light... Small, slow-growing succulent that develops a compact, generally solitary rosette approximately 5–8 cm in diameter, although it may increase in size over the years and produce offsets in cultivation.

The leaves are thick, fleshy, and triangular in cross-section, with broad, translucent tips that form large epidermal windows. These windows have an extraordinarily shiny, almost crystalline surface and can take on a slightly domed appearance, as if they were filled with water. The coloration ranges from grayish-green to shades of dark green, purple, violet, or purplish-brown, especially when exposed to high light levels or experiencing temperature fluctuations.

The internal pattern of the windows combines translucent areas with darker lines and reticulations. This structure allows light to penetrate the photosynthetic tissues located beneath the epidermis, a characteristic adaptation of many Haworthias that grow partially buried.

🌍 Distribution, habitat, and family
Family Asphodelaceae. ‘Tropical Night’ is a horticultural Haworthia hybrid related to springbokvlakensis. Its exact parental combination is not reliably documented, so it should not be attributed to a specific cross without evidence.

Hybrids related to Haworthia springbokvlakensis were developed primarily in specialized horticulture and are especially prized for their combination of translucent windows, epidermal shine, and dark pigmentation. 

As a hybrid cultivar, it has no geographical distribution or natural habitat of its own. Its cultivation requirements are related to the South African Haworthias from which its lineage originates.

❄️ Temperature
USDA Zone 10a–11b. Tolerates minimum temperatures of up to −1 ºC occasionally, provided the plant is dry and protected from moisture. Prolonged exposure to low temperatures should be avoided.

During winter, it is especially important to maintain very well-draining substrate and prevent the combination of cold and moisture from lingering around the roots.

☀️ Lighting
Approximate DLI PAR: 8–15 mol·m⁻²·day⁻¹.

It requires high but filtered or indirect light, avoiding sudden exposure to intense sunlight. Sufficient light promotes compact growth and allows the development of purple tones and the intense transparency of the windows.

Excessively low light can cause the rosette to open and the leaves to lose color intensity. Conversely, too intense solar radiation, especially when accompanied by high temperatures, can cause stress and alter the coloration of the leaves.

💧 Growth cycle and watering
Summer dormancy. It has a spring-autumn growth pattern, with a significant slowdown during periods of intense heat. In summer, when temperatures are high, it may enter a dormant phase and considerably reduce its water consumption. Specialized Japanese sources classify hybrids in this group as plants that grow mainly during spring and autumn.

During periods of active growth, it is recommended to water thoroughly and let the substrate dry out completely before watering again. In summer, if temperatures are very high and the plant remains inactive, watering should be spaced out considerably to prevent root problems.

In early autumn, as temperatures drop, it may gradually regain its activity. During winter, watering should be reduced, especially when temperatures are low.

🌸 Flowering
Flowering occurs via a thin, elongated inflorescence, which can reach approximately 25 cm in length. The flowers are small, tubular, and whitish, with the characteristic greenish or brownish lines typical of Haworthia flowers.

In cultivation, it may flower mainly during spring, although the timing may vary depending on temperature conditions, lighting, and the length of the growing season.

🌿 Nutrition
During the active growth period, Desert CHOICE® Aloes, Haworthias & Co. is recommended, with a high potassium and bioavailable calcium content, applied after watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering. During summer dormancy, fertilization is not recommended.
