Description

Euphorbia resinifera, or Resin Spurge, is a species of spurge with erect succulent stems that, at first glance, have the appearance of cactus. The plant is a dense, slow-growing shrub forming a multi-stemmed, cushion-shaped clump that can grow to 24 inches tall and spreading to 6 feet, 7 inches wide. The ascending branches are pale green with four ridges, short, sharp spines and small, inconspicuous flowers. It is sometimes used as a houseplant.

Resin Spurge has stiff, mounding form. It is generally leafless with the stems providing photosynthesis. The flowers are small, simple, and bright yellow. Flowering is rare out of its native range. It grows best in partial to full sun and is tolerant of alkaline and saline soils; however, soils must be well drained. Little to no additional water is needed during most of the year. Supplemental water is needed only during the hottest months of the summer. Stem cuttings (resin spurge branches profusely and stem segments are readily available). Allow stem segments (propagules) to dry for a week before planting so the wound can seal. Unsealed cuttings, planted too soon, will easily rot before they can grow roots.

Diseases, Insects, and Other Plant Problems:

No known diseases or other plant problems.

    Problems:
    Poisonous to Humans
  • Poisonous to Humans:
    Poison Severity:
    Medium
    Poison Symptoms:
    When ingested, sap from the plant can cause nausea, vomiting, or diarrhea when ingested. If your skin should come in contact with the sap, expect redness, swelling, or blisters after some delay. The plant causes only low toxicity if eaten. Skin irritation is minor and of short duration. Resin euphorbia emits a thick white milky sap known as latex when stems are cut or damaged. The latex is particularly dangerous for the eyes, skin and mucous membranes and will produce burning pain in bones and limbs, paralytic weakness in the joints, and respiratory and skin toxicity.
    Poison Toxic Principle:
    Diterpene esters in milky latex
