    It is easily propagated by cuttings taken in late spring to early summer.

This plant can also be propagated by seed.

  • Special notes:  
    This is easy to grow in well drained soil with full sun. It forms a small, columnar, leafless shrub with sharp spines on the column edges. Stems are green to bluish green. It blooms with small yellow flowers called cymes at the branch tips. The plant slowly spreads from short underground stems. Fruits are tri-lobed and reddish in color. The milky sap of this plant can be irritating to some people, especially be careful to keep it away from one’s face and eyes. This plant has been used for animal fodder when cut into sections and allowed to dry.
