Sedum acre, commonly known as goldmoss stonecrop, goldmoss sedum, biting stonecrop, or wall-pepper, is a perennial plant species found in the family Crassulaceae. It is native to Europe, but has been introduced to North America and other regions as an ornamental plant. Sedum acre is known for its dense, mat-forming growth habit, small, star-shaped yellow flowers, and succulent leaves, which contribute to its ability to withstand drought and poor soil conditions.

Description

Sedum acre is a low-growing, evergreen perennial that can spread to form a dense ground cover. The plant typically reaches heights of 5-10 cm (2-4 inches) and has a spreading habit that can cover large areas. The leaves are small, succulent, and green, often taking on a yellowish or reddish hue in full sun. The flowers are bright yellow, star-shaped, and appear in clusters atop short stems from late spring to early summer. The plant is well adapted to a variety of growing conditions but prefers well-drained soils and full sun.

Habitat and Distribution

Originally from Europe, Sedum acre has a wide natural distribution, extending across many parts of the continent. It is found in a variety of habitats, including rocky outcrops, grasslands, and open forests, often thriving in poor, sandy, or gravelly soils. Due to its attractive appearance and hardiness, it has been introduced to gardens and landscapes in many parts of the world, including North America, where it can sometimes become invasive.

Cultivation and Uses

Sedum acre is popular in cultivation for its drought tolerance, ease of care, and vibrant yellow flowers. It is often used in rock gardens, as a ground cover, in green roofs, or in crevices of stone walls where few other plants can survive. The plant requires minimal maintenance, needing only occasional watering during prolonged dry periods and little to no fertilization. It is also valued for its ability to attract pollinators, such as bees and butterflies, while being resistant to deer and rabbit browsing.

Toxicity

While Sedum acre is often grown for its ornamental value, it is important to note that the plant is toxic if ingested. It contains alkaloids and other compounds that can cause irritation to the skin and mucous membranes. Ingestion can lead to gastrointestinal upset, including vomiting and diarrhea. Caution should be exercised when planting Sedum acre in areas accessible to pets and small children.

Conservation

As a widespread and commonly cultivated species, Sedum acre does not currently face significant conservation threats. However, its ability to spread and establish in new areas means it should be planted with care to avoid potential invasiveness, especially in regions outside its native range.
