Sedum spurium is an herbaceous semi-evergreen plant that is commonly referred to as Two-row Stonecrop.
It is a hardy perennial. Many cultivars of this plant are available for the gardener, and low-growing Sedum species makes an excellent groundcover. As it is slow growing, it may be a better choice to grow than more aggressive species such as Sedum acre (Goldmoss sedum) and Sedum sexangulare (Tasteless stonecrop) which may grow with uncontrolled vigour.
The Sedum genus contains approximately 600 species, and in addition to the aforementioned S. acre and S. sexangulare, other frequently seen species include S. reflexum (Blue stonecrop), S. album (White stonecrop), and S. ternatum (woodland stonecrop); and the commonly grown cultivars Autumn joy; and the wonderful, red stemmed, deciduous upright perennial Sedum Matrona.

In the garden, Sedum spurium is often used as ground cover due to its mat forming properties. However, this is not the only reason to grow the plant. It is a great plant to grow to attract honeybees and butterflies to the garden; it is resistant to rabbits and deer; looks good in a rock garden, at the front of borders, or in a container; helps to maintain soil structure; and is drought tolerant.
Some commonly grown cultivars include Dragon's Blood (leaves turn to red, red flowers), Tricolor (green leaves with pink and white edges, pink flowers), Voodoo (purple leaves, rose-red flowers), and Red Carpet (green leaves develop red edges, turn to red in the summer, and to purple in the autumn).

Sedum spurium is a matt forming low-growing herbaceous perennial that ranges in height from three to six inches (7.5–15 cm), and has a spread of sixteen to twenty-four inches (40–60 cm). It has a slow to medium growth rate.
The leaves of Sedum are colorful and vary between different cultivars and the season. They are thick, simple, succulent, obovate, alternate, and toothed towards their ends; they are about 1 inch (2.5 cm) in length. They often start as green, develop a red edge, and become fully filled with red, burgundy or bronze colors in autumn and winter. This makes them a nice plant to grow to add some late-season color to the garden.

Plants blooms are infrequent from late spring through to mid-summer (sometime late summer). Clustered flowers appear on cymes, are tiny (3/4 inch (1.8 cm)), and star-like. They are usually colored rose or red.
