Two Row Stonecrop, scientifically known as Sedum spurium, is an adaptable succulent groundcover. Gardeners value this plant for its low-maintenance nature, attractive foliage, and ability to thrive in various conditions. It is a favored choice for adding texture and color to many garden settings.
Understanding Two Row Stonecrop
Two Row Stonecrop is a mat-forming perennial succulent, growing 3 to 6 inches tall and spreading 12 to 24 inches wide. Its leaves are thick and fleshy, often displaying green, bronze, or reddish tints that can deepen to burgundy or plum in cooler temperatures or full sun. The common name “Two Row Stonecrop” comes from the arrangement of its leaves in two rows along the stems.
In summer, Sedum spurium produces clusters of small, star-shaped flowers, usually pink, red, or white, depending on the cultivar. These blooms attract pollinators like bees and butterflies. The plant is hardy in USDA Zones 3 to 9. It withstands drought and is used in rock gardens, borders, and as groundcover between pavers.
Planting and Care
Two Row Stonecrop thrives in full sun, which promotes denser growth and vibrant foliage color, though it can tolerate partial shade. Good air circulation is beneficial, especially in humid environments, to prevent fungal issues. The plant prefers well-draining soil and tolerates poor, sandy, or rocky conditions. Avoid heavy, water-retentive soils, as they can lead to root rot. A slightly acidic to neutral soil pH, around 6.0 to 7.0, is suitable.
For new plantings, water once a week to help the plant establish a strong root system. Once established, Two Row Stonecrop is highly drought-tolerant and only requires supplemental watering during prolonged dry spells or extreme heat. Allow the soil to dry completely between waterings to prevent root rot.
Fertilization is rarely needed for Sedum spurium as it performs well in lean conditions. If growth seems slow or more blooms are desired, a light application of a balanced, slow-release fertilizer in early spring can be applied. Avoid over-fertilizing, which can lead to leggy growth. Pruning is minimal; trim as needed to maintain shape or control spread, especially if it begins to overtake other plants. Removing spent flower heads is not necessary for plant health but can be done for aesthetics.
Common Issues and Solutions
Two Row Stonecrop is resistant to pests and diseases, but certain environmental conditions can lead to problems. Overwatering is a common issue, often resulting in root rot. To prevent this, ensure the soil dries out between waterings and use well-draining soil. If root rot is suspected, reducing watering and improving drainage can help.
Inadequate light can cause the plant to become leggy, stretching towards a light source with sparse foliage and reduced flowering. Move the plant to a location with more direct sunlight to address this. Pests such as aphids, mealybugs, slugs, and snails can affect Two Row Stonecrop. These can be managed by hand-picking, a strong spray of water, or insecticidal soap for persistent infestations.
Propagation
Two Row Stonecrop is easy to propagate, primarily through stem cuttings or division. Stem cuttings can be taken in late spring or early summer from healthy, non-flowering stems. Cut a section of stem about 3 to 6 inches long, remove the bottom leaves to expose a few nodes, and allow the cut end to callus for a day or two to prevent rot. Plant the callused cutting in well-draining soil, keeping it lightly moist until roots develop, which takes a few weeks.
Division is another effective method, especially for established clumps that may be thinning in the center. This is best done in spring or fall. Carefully dig up the plant, separate the clump into smaller sections, ensuring each section has roots and some foliage. Replant these sections at the same depth as the original plant and water thoroughly until they establish.
