Sedum hemsleyanum is a succulent that forms rosettes of green leaves covered with short soft hairs. The rosettes elongate into an erect, up to 16 inches (40 cm) tall flower spike with small flowers. They produce offsets near the base of the flowering branches to form small clumps. Leaves can turn reddish in winter. They are lance-shaped, up to 2.4 inches (6 cm) long, and up to 0.5 inches (1.3 cm) wide. Flowers appear in winter and have white petals with partly green keel and red or sometimes yellow anthers.

The specific epithet "hemsleyanum" honors William Botting Hemsley (1843-1924), an English botanist, Keeper of the Herbarium at Kew, and Victoria Medal of Honour in Horticulture recipient.

How to Grow and Care for Sedum hemsleyanum

Light: These succulents grow best in locations where they will enjoy the full sun at least six or more hours per day. Most species will tolerate partial shade but will not thrive in deep shade.

Soil: Sedums do not like to sit in waterlogged soil, so drainage is essential to prevent root rot. Choose a gritty, well-draining soil.

Hardiness: Sedum hemsleyanum can withstand temperatures as low as 0 to 40 °F (-17.8 to 4.4 °C), USDA hardiness zones 7a to 10b.

Watering: Sedum plants are drought-tolerant but do need some water. They do their best with regular watering from spring through fall. Water thoroughly and wait for the soil to dry out before watering again.

Fertilizing: A balanced organic fertilizer each spring is generally all Sedums require. As long the plants are divided annually and provided with fresh soil, feeding is not necessary.

Repotting: Sedums in containers do require little more care than those in gardens. Repot your plants when they outgrow their current pot by moving them out to a larger container to hold the plant better.

Propagation: Once you have one Sedum, it is easy to make more taking stems or leaf cuttings and dividing the plant. Sedums are also easy to grow from seed.
