Sedum aetnense is a small annual succulent with erect or ascending, usually simple stems covered with fleshy erect-appressed leaves. It grows up to 2.4 inches (6 cm) tall. Leaves are glaucous, dark green, or red-tinged. They are conical-oblong, up to 0.2 inches (0.5 cm) long, and often with ciliate or finely dentate margins. Flowers are 4- to 5-merous with white, sometimes red-tinged petals and yellowish or red anthers. They appear in summer in cymose inflorescences, usually consisting of one or in large specimens, often two or more cincinni.
The specific epithet "aetnense (AN-yoo-um)" means "of or from Etna" and refers to Mount Etna, or simply Etna, one of the world's most active volcanoes on the east coast of Sicily in Italy, which is the type locality of the species.
How to Grow and Care for Sedum aetnense
Light: Although widespread in the wild, S. annuum is not cultivated much. It grows best in locations where it will enjoy the full sun for at least six hours daily.
Soil: S. aetnense 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 grows as an annual plant, S. aetnense can be propagated only from seeds.
