Sedum acre ‘Aureum’, often known as Gold Moss Sedum or Golden Stonecrop, offers a vibrant, low-growing succulent groundcover. This adaptable plant brings a cheerful splash of color to various garden settings. Its resilient nature and distinctive appearance make it a popular choice for gardeners seeking both beauty and ease of care.
Understanding Sedum Acre Aureum
Sedum acre ‘Aureum’ is characterized by its small, fleshy leaves that present a striking chartreuse to golden-yellow hue, especially on new growth. These tiny, succulent leaves overlap, forming a dense, moss-like mat that typically reaches a height of 2 to 4 inches. In late spring to early summer, the plant produces abundant small, star-shaped yellow flowers that bloom just above the foliage, adding to its visual appeal. This low-growing perennial spreads readily, creating a carpet-like effect across the landscape. It thrives across USDA Zones 3 to 9.
Cultivation and Care
For optimal color intensity, Sedum acre ‘Aureum’ prefers a location that receives full sun exposure for at least six hours daily. While it can tolerate partial shade, the golden coloration of its foliage may be less pronounced in such conditions. The plant requires well-draining soil and adapts well to poor, rocky, or sandy substrates, making it suitable for challenging garden areas. Conversely, it does not tolerate heavy, wet clay soils, which can lead to root rot.
Once established, Golden Stonecrop is highly drought-tolerant, storing water within its fleshy leaves. Infrequent watering is sufficient; the soil needs to dry out completely between waterings. Overwatering is the most common cause of root rot for this succulent. It is resilient to both high heat and cold temperatures. Fertilization is rarely necessary; however, if growth appears sluggish, a very light application of a balanced fertilizer in the spring can be considered, though it is often unnecessary for healthy development.
Landscaping Uses and Benefits
Sedum acre ‘Aureum’ excels as a low-maintenance groundcover, particularly in dry areas where many other plants struggle to thrive. Its mat-forming habit provides effective weed suppression and year-round visual interest. The plant is an excellent choice for rock gardens, alpine gardens, and xeriscapes due to its inherent drought tolerance and preference for well-drained conditions.
This versatile succulent can also be strategically planted in wall crevices or between stepping stones, softening hardscape elements and providing a charming golden accent. In container arrangements, it functions effectively as a “spiller,” trailing over the edges, and it is also suitable for green roof systems. Its dense growth on slopes can contribute to soil stabilization, aiding in erosion control. Benefits include its general resistance to deer and rabbits, making it a reliable addition to many landscapes.
Propagation and Maintenance
Propagating Sedum acre ‘Aureum’ is remarkably straightforward. Stem cuttings can be taken and simply laid on the soil surface, where they will readily root. Alternatively, larger clumps of the plant can be divided, offering another easy method for multiplication. The plant also exhibits a self-propagating nature, as its stems will root wherever they come into contact with the ground, contributing to its spreading habit.
Pruning is seldom required, primarily involving light trimming to manage its spread or to tidy the plant after its flowering period. The plant shows general resistance to most common pests and diseases. While generally trouble-free, it is advisable to monitor its vigorous spreading habit to prevent it from encroaching on less robust neighboring plants.
