🌱 Morphology
    Hybrid succulent that forms compact rosettes approximately 10–15 cm in diameter. Its fleshy, obovate, light green to bluish-green leaves feature wavy and ruffled margins, which become more pronounced with maturity. The edges take on red or carmine tones under intense light and in cool temperatures. The leaves end in a small mucron, a short tip that helps distinguish it from other ruffled-leaved cultivars. Over time, it can produce offsets and form clusters of rosettes.

🌍 Distribution, habitat, and family
Hybrid cultivar of horticultural origin, attributed to breeder Harry Butterfield in California during the 1950s. I have not found sufficiently reliable parental lineage to confirm its parents. It belongs to the Crassulaceae family. It has no native wild distribution or assigned taxonomic series.

❄️ Temperature
USDA 10a (−1.1°C) as a conservative cultivation reference. It should be protected from frost, and the substrate kept dry during cold spells. The USDA zone limit does not guarantee the individual tolerance of the plant.

☀️ Lighting
Bright partial shade, DLI PAR 12–20 mol·m⁻²·day⁻¹. Abundant light promotes a compact shape and reddish edges. It can receive gentle morning sun with gradual acclimatization, but it should be protected from intense summer sun to prevent scorching.

💧 Growth cycle and watering
Opportunistic, with growth favored by moderate temperatures. Water thoroughly and allow the substrate to dry out completely before watering again. Reduce watering during cold periods and heatwaves. Prevent water from remaining trapped between the ruffled leaves, where it can promote rot.

🌸 Flowering
It can produce flower stalks with bell-shaped yellow or orange flowers, characteristic of many echeverias. 

🌿 Nutrition
During the active growth period, Desert CHOICE® Succulents is recommended, applied after watering. Before flowering, it can be supplemented with Desert CHOICE® Flowering. Fertilizing is not recommended during winter dormancy.
