Euphorbia Seguieriana subsp. Niciciana, Siberian Spurge, Euphorbia Reflexa, Yellow flowers, Drought tolerant perennial, Deer resistant perennial, rabbit resistant perennial

Notable for its peculiar flowers and handsome foliage, Siberian Spurge (Euphorbia seguieriana subsp. niciciana) is an upright, bushy, clump-forming perennial perfect for brightening any border. It produces exceptionally eye-catching clusters of bright lime-green flowers in late spring, which last for months. The semi-evergreen foliage of narrow, blue-green leaves radiates from exquisitely branched mahogany-red stems and combines attractively with ornamental grasses, Alliums, or Lavenders.

  • Typically grows up to 12-18 in. tall and wide (30-45 cm)
  • Remaining attractive during all its growing season, this remarkable plant is resilient to most pests and diseases, is drought (once established), deer and rabbit tolerant, and is easy to care for.
  • Performs best in full sun in fertile, well-drained soils. This species is not fussy about soil conditions as long as they are well drained.
  • Perfect addition to beds, borders, containerscottage gardens, or Mediterranean Gardens.
  • Remove the faded flower heads after blooming is over. Prune to the ground in the fall. Self-seeds freely if not deadheaded.
  • All parts of the plant are highly toxic if ingested. The milky sap may irritate the skin and eyes.
