Description

Euphorbia cyparissias, or Cypress Spurge, is a herbaceous perennial herb with erect stems, narrow leaves, and yellow, crescent-shaped glands on the rim of its cup-shaped flowers. The mature plant resembles small spruce or cypress tree. The soft, needle-like foliage is much like a bottlebrush in appearance and the chartreuse flowers crowd together at the tips of the stems. Note that the milky latex sap that seeps from broken leaves and stems can be toxic to skin and eyes. Be sure to wear gloves and eye protection when handling this plant

Cypress Spurge grows best in dry, well-drained soils in full sun. The plant tolerates poor soils, including rocky, sandy ones. It spreads by rhizomes and can be quite invasive, particularly in rich, moist soils, and freely reseeds. Eight to ten plants per square yard are sufficient to quickly form a dense ground cover. It tolerates drought and can often be found on dry banks and hillsides where little else will grow.

Diseases, Insects, and Other Plant Problems:

Cypress Surge is relatively pest and disease-free. It is a quickly spreading perennial that can overwhelm other, nearby, perennials.
