Description
Echeveria subcorymbosa 'Lau 30' is a small succulent that forms compact, short-stemmed rosettes of glaucous, bluish-grey leaves with reddish margins and often red-flecked on the lower surface. The brown stem can grow up to 2 inches (5 cm) tall, while the rosettes are usually about 1.2 inches (3 cm) in diameter. The leaves are ascending or upcurved, spoon-shaped, ending in a sharp point.
The flowers are egg-shaped, reddish-orange in the lower portion, yellow in the upper part, and can reach about 0.6 inches (1.5 cm) in length and 0.3 inches (0.8 cm) in diameter. They appear on stalks with few bracts in summer. The flower stalks can grow up to 4.4 inches (11 cm) long.
How to Grow and Care for Echeveria subcorymbosa 'Lau 30'
Light: E. subcorymbosa 'Lau 30' prefers full sun to partial shade. If you move your plant outside in the spring, do it gradually. The intense afternoon sun can cause sunburn. During the winter, when your E. subcorymbosa 'Lau 30' is inside, put it near the brightest window in your home. It will stretch if it does not have enough sunlight.
Soil: This succulent needs a potting soil mix that drains quickly. Many growers will create their own mix. However, commercial succulent potting mixes will work fine.
Temperature: This plant is a tender succulent, which means it must be brought indoors for the winter to survive. E. subcorymbosa 'Lau 30' can withstand temperatures as low as 30 °F (-1.1 °C). USDA Plant Hardiness Zones 10a to 11b, 30 to 50 °F (-1.1 to 10 °C).
Watering: Provide moderate amounts of water from spring to fall. The "soak and dry" method is the preferred schedule for watering E. subcorymbosa 'Lau 30'. If you have saucers under the pots, empty the water briefly. Water your plant just enough to keep it from shriveling during winter.
Fertilizing: E. subcorymbosa 'Lau 30' grows well without fertilizer but may benefit from the extra nutrients. Use a slow-release fertilizer in spring or a liquid fertilizer diluted 2 to 4 times more than usual and used less often than recommended.
Repotting: Repot the plant only as needed during spring or early summer when it grows actively. To repot your E. subcorymbosa 'Lau 30', ensure the soil is dry before repotting.
Propagation: Like all Echeverias, this succulent is usually propagated from leaves and offsets, but it can also be grown from stem cuttings and seeds. Spring is the best time to take cuttings and separate offsets. Sow the seeds in spring or summer.
