This species is native to Mexico (Coahuila, Nuevo Leon, San Luis Potosi and Hidalgo).


Sedum diffusum is a mat-forming succulent with fleshy, widely branching rootstock and short stems with slender green to pink branches that bear glaucous-blue leaves. It grows up to 7 inches (17.5 cm) tall and is more compact than Sedum diffusum 'Potosinum'. Leaves are up to 0.5 inches (1.3 cm) long and up to 0.12 inches (0.3 cm) in diameter. The old leaves turn pinkish, then ashy white. Flowers are white, star-shaped, and appear in summer on scorpioid branches.

The specific epithet "diffusum" derives from the Latin "diffusus," meaning "diffused or spread" and refers to the growth habit of the species.

How to Grow and Care for Sedum diffusum

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 diffusum can withstand temperatures as low as 0 to 30 °F (-17.8 to -1.1 °C), USDA hardiness zones 7a to 9b.

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.
