Euphorbia dendroides

A tender, deciduous semi-succulent shrub with red, woody, branched stems to 2m (6½ft) high and across, forming a canopy when mature. The simple leaves are green and produced in whirls at the ends of the branches and change to fiery red and orange in autumn before falling. Clusters of bright green-yellow floral bracts are produced in spring on the tips of the stems, which then branch into two below the old flower heads, once flowering has finished. Being frost-tender and growing to a large size, this makes it useful for growing as an architectural specimen plant for a frost-free conservatory, greenhouse or large, sunny room indoors

How to grow

Cultivation

Grows best in containers in a frost-free location in well-drained soil, in full sun. Watering should be moderate over winter to avoid soil remaining too wet for too long and the roots rotting.

Propagation

Propagate by cuttings in spring or early summer; dip cut surfaces in charcoal or lukewarm water to prevent bleeding

Suggested planting locations and garden types
  • Mediterranean climate plants
  • Patio and container plants
  • Conservatory and greenhouse
Pruning

Pruning group 1 - minimal pruning is required, as the shrub develops naturally into a neat dome shaped bush.
