Sempervivum tectorum – The Resilient and Beautiful Houseleek

Native to the mountains of Europe, Sempervivum tectorum thrives in rocky, dry conditions and has earned the nickname “Houseleek” for its historical use as a roof protector, believed to guard against lightning and fire. Its rosettes are thick, fleshy, and tightly packed, forming stunning clusters over time.

The plant blooms once in its life, producing star-shaped flowers in shades of pink, red, or yellow. After flowering, the main rosette dies, but not to worry—the surrounding “chicks” ensure the plant continues to thrive.

Plant Care Tips

Light:
Enjoys full sun to partial shade. The more sunlight it receives, the more vibrant the colors become, with hues of red and purple appearing on the leaves.

Watering:
Water thoroughly when the soil is dry to the touch. This plant is drought-tolerant and thrives on infrequent watering. During the winter months, reduce watering significantly.

Soil:
Requires well-draining soil—cactus or succulent mixes are perfect. Make sure to avoid soggy conditions, as this can lead to rot.

Temperature:
Prefers cool to moderate temperatures (15–24°C). Tolerates frost well and can handle a light freeze, making it ideal for outdoor gardens in many climates.

Humidity:
Low humidity is best. Avoid areas with excessive moisture like bathrooms or kitchens.

Fertilizer:
Feed sparingly with a diluted, balanced fertilizer once a month during the growing season (spring and summer). No need to fertilize in winter.

Pests: While rarely a problem, aphids or mealybugs can sometimes appear. Treat with neem oil or insecticidal soap if necessary.
