Sedum annuum is an annual or rarely biennial succulent with erect stems that bear pea green or red-tinged leaves. It grows up to 8 inches (20 cm) tall. The stems are simple or branched from the base. Leaves are thick, fleshy, linear-oblong or oblong-elliptic, sessile with a short, broad truncate spur, and up to 0.25 inches (0.6 cm) long. Flowers are yellow, sometimes tinged with red. They are star-shaped, 5-merous, and appear in lax cymes with 3 to 15 flowers on 1 to 3 branches in summer.
The specific epithet "annuum (AN-yoo-um)" is the neuter form of the Latin adjective "annuus," meaning "annual, yearly, lasting a year," and refers to the life cycle of the species.
How to Grow and Care for Sedum annuum
Light: Although common and widespread in the wild, S. annuum is not much cultivated. It grows best in locations where it will enjoy the full sun for at least six hours per day.
Soil: S. annuum does not like to sit in waterlogged soil, so drainage is essential to prevent root rot. Choose a well-draining soil mix.
Watering: From spring through fall, water thoroughly and wait for the soil to dry out before watering again. Avoid wetting the leaves, stems, and flowers when watering.
Propagation: Since it usually grows as an annual plant, S. annuum can be propagated only from seeds.
