About Graptosedum 'Miul'
Graptosedum 'Miul' is an interspecific hybrid succulent belonging to the Crassulaceae family, renowned for its sculptural foliage and adaptive growth habit. This cultivar forms dense, symmetrical rosettes composed of fleshy, paddle-shaped leaves exhibiting a soft bluish-green base tone. Under optimal light exposure, the leaf margins and tips develop a delicate apricot-pink blush, creating a striking bicolor effect. Mature specimens produce slender inflorescences in late spring to early summer, bearing small, stellate flowers in pale yellow to cream hues. Its compact size and visually dynamic coloration make it a versatile choice for both novice and experienced collectors.
How to Care for Graptosedum 'Miul'
Light: Graptosedum 'Miul' requires abundant bright, direct sunlight for 4-6 hours daily to maintain compact growth and vibrant coloration. An east or south-facing windowsill provides ideal exposure indoors, while partial afternoon shade is advisable in regions with intense summer heat (USDA zones 10-11) to prevent leaf scorch.
Water: Thorough but infrequent watering is essential, allowing the soil to dry completely between applications. During active growth (spring-fall), deep watering every 10-14 days is typically sufficient. Reduce frequency to monthly in winter dormancy. Always avoid water accumulation in the rosette core to mitigate rot risks.
Temperature: This hybrid thrives in temperatures between 65°F and 80°F (18°C-27°C). It exhibits moderate cold tolerance down to 40°F (4°C) briefly but requires protection from frost. Prolonged exposure above 90°F (32°C) necessitates enhanced airflow and reduced direct sun exposure.
Soil & Potting: A well-draining mineral substrate is critical. Utilize a cactus/succulent mix amended with 40-50% perlite or pumice. Select containers 1-2 inches wider than the rosette diameter, preferably unglazed terracotta pots with drainage holes to promote evaporation. Light-colored pots further mitigate root zone heat accumulation.
Fertilizer: Apply a balanced, water-soluble fertilizer diluted to 50% strength (e.g., 5-10-5 NPK) every 6-8 weeks during the growing season. Discontinue feeding from late fall through winter to align with natural dormancy cycles.
Pests & Disease: Graptosedum 'Miul' demonstrates good resistance to pests but may occasionally attract mealybugs or aphids. Early infestations respond to neem oil applications. Root rot from overwatering represents the primary disease concern, preventable through strict adherence to dry-down cycles and porous soil composition.
Propagation: Leaf propagation yields the highest success rates. Gently detach healthy lower leaves, allow callusing for 2-3 days, then place on dry substrate. Mist lightly after 10 days once initial roots emerge. Rosette division is feasible for mature, clustered specimens during repotting.
