How to care for euphorbias

Euphorbias do not require feeding or special care as long as the growing conditions are right. Cut back flowering stems after the blooms have faded. Always wear gloves when working with euphorbias as the milky sap they produce when cut irritates the skin and is poisonous if ingested. Follow our guide to pruning euphorbias.

Great euphorbia varieties to grow

  • Euphorbia x martini ‘Ascot Rainbow’ – with dark grey-green rosettes of leaves and upright bracts in lime-green with a red eye. They emerge with a pink flush and develop a red-marked, creamy yellow margin with age. They may also develop pink colouring in winter. The spring flowerheads are variegated green, cream and red. It forms a low, weed-smothering carpet over the ground.
  • Euphorbia myrsintes –small and drought-tolerant, E. myrsinites is good for bordering paths or patios, alpine gardens and containers. It has elongated silvery-green fir cones, with pale silvery green scale-like leaves overlapping all the way along the stems. In early summer these have typical flat heads of yellow euphorbia flowers at the ends.
  • Euphorbia x pasteurii – a large evergreen shrub, this is a cross between Euphorbia stygiana and Euphorbia mellifera. It is rounded in shape and slender, with dark green leaves with white mid ribs, turning red in autumn. Flowers are bronze/green and sweetly scented. Grow Euphorbia x pasteurii in well-drained soil in a Mediterranean style or gravel garden. Cut back spent flower heads in autumn.
  • Euphorbia amygdaloides var. robbiae – a dark, evergreen variety that thrives in poor dry soil in shade, making it perfect for growing under big trees. It spreads by underground runners, eventually forming a low weed smothering carpet. Lime green flowers appear from spring to early summer.
  • Euphorbia characias subsp. wulfenii – an architectural perennial, with bluish-green evergreen foliage and large, dome-shaped, lime-coloured flowers in spring. It’s ideal for growing in a sunny border or gravel garden.
