Echeveria Blue Elf (Sedeveria 'Blue Elf') is a compact hybrid succulent with teal-green rosettes and pink-red tips, thriving in USDA zones 9a-11. It needs bright sunlight (6+ hours daily), well-draining soil, and infrequent watering (every 1-2 weeks when soil is dry). Ideal temperatures are 60-80°F (15-27°C), with low humidity and protection from frost. Fertilize in spring and summer with diluted fertilizer, avoiding winter feeding. Overwatering can cause root rot, while pests like mealybugs can be treated with neem oil. This non-toxic plant is easy to propagate through leaf cuttings or offsets.
