A source of fascination in the garden for its interesting flower heads, Cypress Spurge (Euphorbia cyparissias) is a very showy perennial which enjoys months of fragrant chartreuse flowers. A forest of tiny flowers held in umbel-like clusters appear in spring or early summer, consisting primarily of glowing lime-yellow bracts that slowly fade to red-orange as they mature. The foliage resembles that of a miniature cypress tree, hence its common name.

  • Typically growing up to 12 in. (30 cm), Cypress Spurge is an erect, branching, rhizomatous plant which can rapidly spread to form a bushy ground cover. So, give it its own space as it is an aggressive grower!
  • Remaining attractive during all its growing season, this remarkable plant is resilient to most pests and diseases, is drought, deer & rabbit tolerant and is easy to care for.
