Golden Sedum (Sedum acre ‘Aureum’) is a popular and effective ground cover. This succulent perennial is admired for its bright yellow-green foliage, which shifts to buttery yellow in full sun and warmer temperatures. Its low-growing, mat-forming habit creates a visually appealing carpet, making it a favored option for various landscape applications. Golden Sedum’s low-maintenance nature makes it accessible for all gardeners, offering both aesthetic charm and practical benefits.
Understanding Golden Sedum as Ground Cover
Golden Sedum features tangled stems with small, conical leaves, typically green but tipped with bright golden yellow, especially in spring. This foliage grows up to 3 inches tall, forming a dense, ground-hugging mat that spreads 8 to 24 inches wide. In summer, tiny, star-shaped golden yellow flowers emerge just above the foliage, attracting pollinators like bees and butterflies.
This Sedum acre cultivar is hardy, thriving across USDA zones 3 to 8. It is semi-evergreen, retaining color in warmer climates. Its succulent nature allows it to store water, providing drought tolerance once established. Golden Sedum controls erosion, especially on slopes, and its dense coverage helps suppress weeds. It adapts well to challenging sites like rock gardens, shallow soils, and areas with poor fertility.
Planting Golden Sedum
Planting Golden Sedum successfully requires careful site selection and soil preparation. It performs best in full sun, needing at least six hours of direct sunlight daily, though it tolerates some partial shade. Ample sun exposure enhances its vibrant golden hues. Excellent drainage is crucial, as Golden Sedum is susceptible to root rot in waterlogged conditions.
Golden Sedum thrives in poor to moderately fertile, well-draining soils, including gritty, rocky, or sandy compositions. Amend heavy clay soils with sand, grit, or perlite to improve drainage. When planting from cuttings, plugs, or divisions, space plants approximately 7 inches apart for quick coverage. For cuttings, allow them to dry for a day or two before planting in well-draining soil, keeping it lightly moist until roots form. After planting, water thoroughly to settle the soil, but avoid overwatering.
Ongoing Care and Maintenance
Once established, Golden Sedum requires minimal care. Watering needs are infrequent for mature plants; they are drought-tolerant and store water in their fleshy leaves. Allow the soil to dry out completely between waterings, as excessive moisture can lead to root rot. During prolonged dry spells in summer, occasional deep watering, perhaps once every two weeks, may be beneficial, but only if the top two inches of soil are dry.
Fertilization is unnecessary for Golden Sedum, as it performs well in nutrient-poor soils. Overly rich soil can lead to weak, leggy growth instead of a dense mat. Light pruning or trimming can be done as needed to maintain shape, control spread, or remove spent flowers. This plant is hardy and requires little winter care, as its semi-evergreen foliage provides interest through colder months in many zones.
Troubleshooting Common Issues
While Golden Sedum is resilient, issues primarily arise from improper watering. The most frequent problem is overwatering, leading to root rot and a mushy appearance. This occurs because prolonged saturation deprives roots of oxygen, causing them to decay. Ensuring well-draining soil and allowing it to dry out between waterings is the primary solution.
Poor drainage exacerbates overwatering problems, as standing water quickly damages the plant. If the plant appears drooping or wilting, it indicates stress from too much or too little water, or unsuitable environmental conditions. While Golden Sedum is resistant to most pests and diseases, excessive moisture can lead to fungal spots. Should pests like aphids or mealybugs appear, they can be managed with insecticidal soap or neem oil applications.
