Needle stonecrop (Sedum rupestre ‘Angelina’) is a popular succulent groundcover known for its ease of care and striking appearance. It provides vibrant, year-round color and forms a dense mat, making it an excellent, low-maintenance choice for diverse garden settings.
Understanding Needle Stonecrop
Needle stonecrop is distinguished by its unique, needle-like succulent leaves. These leaves display a chartreuse to golden-yellow hue, intensifying to vibrant orange or reddish tones in cooler temperatures or strong sunlight. This evergreen perennial maintains colorful foliage year-round. It forms a low, spreading mat, typically reaching 4 to 6 inches tall and spreading 1 to 3 feet wide. Small, star-shaped yellow flowers may appear on upright stems in mid to late summer, but the foliage is its primary ornamental feature.
Growing and Caring for Needle Stonecrop
Needle stonecrop thrives in full sun, ideally six or more hours daily. While it tolerates some partial shade, excessive shade can cause its vibrant yellow foliage to revert to lime green and lead to leggy growth, also diminishing its color.
Well-draining soil is essential for this succulent, as it is highly susceptible to root rot in overly wet conditions. It performs well in poor, rocky, or sandy soils and does not require rich soil. The plant tolerates a soil pH from slightly acidic to neutral (6.0-7.0).
Once established, needle stonecrop is exceptionally drought-tolerant, storing water in its fleshy leaves. Young plants require regular watering during their first year to establish roots. After establishment, supplemental watering is only necessary during prolonged hot, dry periods, allowing the soil to dry completely between waterings. Overwatering is a common issue.
This plant is hardy, thriving in USDA Zones 5 through 9, and tolerates both heat and cold. Some sources indicate hardiness down to USDA Zone 3. It also demonstrates resilience in various environmental conditions, including urban pollution.
Needle stonecrop generally does not require fertilization. If soil fertility is very low, a minimal application of a balanced granular fertilizer in early spring can be beneficial. Excessive fertilization leads to weak, leggy growth.
Pruning requirements are minimal. It can be pruned to maintain shape, contain spread, or remove dead or damaged foliage. The plant’s fragile stems break easily, often rooting where they touch the soil, aiding its spreading habit.
Needle stonecrop is generally resistant to most pests and diseases. Root rot is the primary concern, occurring due to consistently wet or poorly draining soil. Slugs and snails may occasionally be a problem.
Landscaping with Needle Stonecrop
Needle stonecrop serves as an excellent groundcover, quickly forming a dense mat of foliage. Its spreading habit effectively fills spaces and suppresses weeds. It is well-suited for rock gardens, growing in rocky, gravelly areas and spilling over stones.
This plant is also effective along pathways, in perennial borders, or as edging. Its trailing nature makes it suitable for containers and hanging baskets, where its vibrant foliage cascades attractively. For water-wise landscaping, needle stonecrop is a good choice for xeriscaping. It can also be used for erosion control on slopes to stabilize soil.
