  • Uses:  
    This plant makes a nice low ground cover succulent where it is hardy. Its repeated regular, rectangular stems of even low height create a strong pattern in the landscape making it a fine choice for cactus, succulent and xeriscape gardens. It also makes a nice container plant. Euphorbia resinifera has small spines and caustic sap so it is best located away from foot traffic. Impervious to deer and rodents.
  • Propagation:  
    Propagated by cuttings taken in late spring to early summer. As with most succulent and cacti cuttings the wound needs to have time to dry and callus over; then plant the cutting in loose, well draining cactus soil and give it time to root. Can also be propagated by seed sown indoors in early spring.
  • Problems:  
    Needs good drainage
  • Special notes:  
    Euphorbia resinifera becomes a dense suckering succulent shrub. The stems are a light-green to gray-blue color, almost square, and covered with small brown spines arranged in cymes. It has been in cultivation in California for many years. The plant flowers in summer with small yellow blooms the stems of which dry and become spine-like. This plant's sap contains a high concentration of the toxin resiniferatoxin which is being used as a starting point in the development of a novel class of analgesics. Recent research has shown that this toxin exhibits its effects in a similar fashion to capsaicin, the primary compound found in hot peppers. It is up to one thousand times stronger than pure capsaicin. So all parts of plant are poisonous if ingested and handling the plant may cause skin irritation or allergic reactions.
