Description

Euphorbia cyparissias, or Cypress Spurge, is a perennial herb with erect stems, narrow leaves, and yellow, crescent-shaped glands on the rim of its cup-shaped flowers. The mature plant resembles a small spruce or cypress tree.

Cypress Spurge is toxic. Stems and leaves contain sap that can cause nausea, vomiting, and diarrhea if ingested. When the plant and its sap come in contact with skin, it can cause redness, swelling, and blisters after some delay.

Cypress Surge is a quickly spreading plant that can overwhelm other, nearby, perennials. The USDA has identified Cypress Surge as invasive in more than 20 counties throughout North Carolina.

Quick ID Hints:

  • Soft, needle-like foliage looks like bottlebrush
  • Chartreuse flowers crowded at tips of stems
  • Milky white latex sap from broken leaves and stem

Herbaceous perennial to 1', softly dense and spreading.  

Blooms in late spring to early summer; leaves are whorl-like and soft, resembling a large bottlebrush; white, milky latex sap from broken stems and foliage may irritate skin; spreads by underground stems and can be invasive in fertile soils. 

Tolerates drought and dry banks where little else will grow; relatively pest/disease-free.
