Sedum oaxacanum

Sedum oaxacanum is an evergreen succulent in the Crassulaceae family. It comes from Puebla and Oaxaca in Mexico. Its native range has a seasonally dry tropical climate. Kew lists it as a succulent subshrub. The RHS describes its garden form as a mat-forming perennial. It keeps its leaves through the year and forms low cover.

The green leaves grow in rosettes shaped like stars. Their tips have a white, powdery look. This pale detail contrasts with the rest of each leaf. The RHS gives a garden height of 0.3–1.6 feet [0.1–0.5 metres]. It lists the same range for the plant's spread. Plants take two to five years to reach full size. These dimensions suit smaller planting spaces as well as pots. Its mat-forming habit gives it a different outline from upright succulents.

Yellow flowers open in spring and summer. Each flower has a star-like shape, echoing the leaf rosettes. The flowers add seasonal colour above the evergreen growth. The leaf colour remains part of the display outside flowering time. Both the leaves and flowers contribute to its garden value. The supplied account gives no details about its fruit or seeds.

Grow this species in full sun with soil that drains well. The RHS recommends moderate soil fertility and a neutral to alkaline pH. It lists chalk, loam and sand as suitable soil types. South-facing and west-facing sites suit its need for sun. The site may be exposed or sheltered. It tolerates drought, though the supplied moisture range includes dry to moist conditions. Drainage remains a key part of the stated growing conditions. The RHS assigns it a UK hardiness rating of H7. That rating covers temperatures below −4°F [−20°C] under UK growing conditions.

Use it in rock gardens, gravel beds or garden borders. It also suits pots, hanging baskets and living walls. The RHS includes indoor and conservatory growing among its uses. Its planting suggestions cover courtyards, cottage gardens and informal beds. No routine pruning is needed. Take stem cuttings in spring to raise more plants. The RHS reports few pest or disease problems in general. This does not mean problems can never occur. The supplied sources do not establish edible uses or toxicity. They also give no medicinal uses for this species.
