🌱 Morphology
   A relatively slow-growing intergeneric hybrid that develops branching stems from the base, forming small terminal rosettes approximately 5–6 cm in diameter. Overall, it can reach about 20 cm in height. The stems are elongated and have a pronounced texture, while the rosettes bear fleshy, obovate, slightly pointed leaves with small cilia along their margins, inherited from one of its parent plants. Young leaves are distributed along the stems, but the older ones tend to fall off as the stems grow and branch.

Coloration varies according to the season and growing conditions: the leaves may be green or grayish green during warm periods, while bright light and cool temperatures encourage intense reddish, coppery, and purple tones on the margins and tips. In winter, the rosette may develop a particularly striking contrast between its green center and purplish-red edges.

🌍 Distribution, habitat, and family
This is a horticultural hybrid of European origin, not a wild species with its own natural range. Its origin is probably linked to British succulent enthusiast Fred Wass, known for his experiments hybridizing Crassulaceae. The plant later circulated among collectors and was named in honor of Letizia Alleruzzo.

Its documented parent plants are Sedum cuspidatum × Echeveria setosa var. ciliata. The former contributes the branching habit and elongated stems; the latter contributes to the formation of rosettes with ciliate leaves. This combination explains its intermediate appearance, distinct from both a compact, basal-rosette Echeveria and a Sedum with leaves distributed along thinner stems.

❄️ Temperature
USDA 9a: −6.7 °C as the zone’s lower climatic limit. This does not mean that the hybrid can safely tolerate this temperature. It is recommended to protect it from prolonged frost and, above all, from cold accompanied by moisture in the substrate. Cool, dry temperatures can intensify the reddish coloration, but should not be mistaken for proven resistance to severe frost.

☀️ Lighting
Full sun · DLI PAR 20–30 mol·m⁻²·day⁻¹. Abundant light encourages compact rosettes and enhances the reddish and purple hues. In summer, if temperatures are very high, it may benefit from protection from the strongest midday sun. It should be gradually acclimated to direct sunlight.

💧 Growth cycle and watering
Opportunistic. It can grow during much of the year if provided with moderate temperatures, sufficient light, and healthy roots. Water thoroughly and allow the substrate to dry out completely before watering again. During intense heat or winter cold, when growth slows, watering should be less frequent. Avoid allowing water to collect in the rosette crowns, and ensure good airflow around the stems.

🌸 Flowering
It produces terminal inflorescences with small, star-shaped, yellow flowers, characteristic of many Crassulaceae in this group. Flowering may occur in spring or during periods of active growth, although there is not enough consistent data to determine the age at which it first flowers or to confirm that it blooms in several flushes during a single season. Its self-fertility has also not been confirmed.

🌿 Nutrition
During the active growing period, we recommend Desert CHOICE® Succulents, applied after watering. Before flowering, it can be supplemented with Desert CHOICE® Bloom. Fertilizing is not recommended during dormancy if growth has stopped.
