Echeveria runyonii is a fast growing rosette-forming succulent, up to 4 inches (10 cm) tall and up to 4 inches (10 cm) in diameter. The leaves are glaucous pinkish-white in color, up to 3.2 inches (8 cm) long and up to 1.6 inches (4 cm) wide. The flowers are bright orange and yellow in color and rise above the foliage on up to 8 inches (20 cm) tall, arching inflorescence, usually in late summer or fall.
Echeverias are very popular succulents that grow in attractive rosettes with beautiful leaves in a variety of colors and sometimes stunning flowers. These plants have been extensively hybridized, so in addition to the main species, there are many varieties that have been specially bred for interesting leaf form and color. Most Echeveria will remain fairly small (a few inches to a foot across), but some species will grow to small shrub-like plants of 2 feet. Members of the Crassulaceae family, their care is similar to sedum and kalanchoe succulents. Growing Conditions Light: Full sun. Perfect for a sunny window. Water: Water during the summer and spring, making sure drainage is immaculate. Reduce water in the winter to monthly. Temperature: Prefers average summer temps (65 degrees F - 70 degrees F). In winter, cool to 50 degrees F. Soil: A well-drained succulent mix, with an ideal pH around 6.0 (slightly acidic). Fertilizer: Feed with a controlled-release fertilizer in the beginning of the season or weekly with a weak liquid solution. Use a balanced 20-20-20 fertilizer at 1/4 strength on mature plants, and a fertilizer with less nitrogen on young plants.
