Euphorbia palustris (Marsh Spurge)

Marsh Spurge, Swamp Spurge, Marsh Euphorbia


Incredibly showy, fast and easy to grow, Euphorbia palustris, commonly called Marsh Spurge or Marsh Euphorbia, is an upright, bushy, clump-forming herbaceous perennial which is perfect to brighten any border. It produces exceptionally eye-catching clusters of bright greenish-yellow flowers in late spring to early summer (depending on regions), which last for months. The foliage of medium green leaves, elegantly radiating from exquisitely branched stems, turns to attractive shades of yellow or orange in fall, providing a long season of interest.

  • Typically grows up to 24-36 in. tall and wide (60-90 cm)
  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society for its outstanding qualities
  • Remaining attractive during all its growing season, this remarkable plant is resilient to most pests and diseases, is drought (once established), deer & rabbit tolerant and is easy to care for.
  • Performs best in full sun or part shade in medium to wet, well-drained soils. This species tolerates heavier soils than most other species of spurge. Wet soils, poor soils (including rock or sandy ones) and some soil dryness are also tolerated!
  • Perfect addition to beds, borders, bog gardens, cottage gardens or Mediterranean Gardens. Great for containers too!
  • Propagate by seed sown in containers in spring. Propagate by division in early spring or take basal cuttings in spring or early summer; dip cut surfaces in charcoal or lukewarm water to prevent bleeding. Self-seeds freely if not deadheaded.
  • All parts of the plant are highly toxic if ingested. The milky sap may cause irritation to skin and eyes.
