Sedum obtusatum: complete guide

Overview

Sedum obtusatum, better known as Sierra stonecrop or Sierran stonecrop, is a stunning alpine succulent from California and Western Nevada. This plant is renowned for its spectacular fall colors, glowing red to orange. Perfect for rock gardens, green roofs, and alpine borders, it offers seasonal color with virtually no maintenance.

Appearance and Bloom

Sierra stonecrop grows as a compact mat 8-20 cm tall. The leaves are green in summer but transform in autumn into a beautiful red-orange spectrum. The flowers are small, cream or yellow, appearing in June-July. This is primarily a foliage plant whose true beauty lies in its fall coloring.

Ideal Location

Plant Sedum obtusatum in full sun. At least 6-8 hours of direct sunlight daily is essential for optimal coloring. In much shade, fall color fades considerably. This is an alpine plant that appreciates intense sunlight.

Soil

Extremely good drainage is essential. Use alpine potting soil or add plenty of gravel, sand, and perlite. This plant naturally grows on rocky slopes at high altitude. A pH between 6.0 and 8.0 is suitable. Prefers poor, well-drained soil.

Watering

Once well established, Sierra stonecrop is highly drought tolerant. Water only minimally, especially during the growing season. In winter, water very little. This is a plant of mountaintops; water is scarce in its natural habitat.

Pruning

Minimal pruning is needed. Remove dead flowers if desired, but this is not essential. The plant maintains its form excellently on its own. Dead foliage in late spring can be removed.

Maintenance Calendar

• March-April: Post-winter inspection, remove dead material
• May-July: Bloom and growth
• August-October: Fall color develops, enjoy!
• November-February: Winter dormancy

Winter Hardiness

Sedum obtusatum is hardy to about -15 to -20 degrees Celsius. This makes it suitable for virtually all European gardens. It is one of the hardiest sedums for European climates.
