    Although I sometimes have issues with other Euphorbias, I find this one easy to grow, providing it's not over watered. Just give it plenty of sun in a spot sheltered from the wind and it grows well without having to fuss over it. I bought a tiny one in the Spring of 2019 and now in the Fall of 2020 it has quadrupled in size. The more sun it gets the brighter the coloring becomes.

    Colorful dwarf version of Pencil Tree (Euphorbia tirucalli) with orange stems. Like the green version of this plant, it grows pencil-like stems with small, ephemeral leaves at the tip. It may not flower in all locations.

    Suitable for container culture. A reasonably large bush when allowed to grow in the ground. Tends to drop branches in the wind. Cold sensitive. Drought tolerant. May revert to the all-green form and grow to a much larger size. Avoid touching the sap, which is a potent irritant.
  • Posted by SongofJoy (Clarksville, TN - Zone 6b) on Feb 4, 2012 3:19 PM concerning plant:
    The milky sap of this plant is extremely irritating to the skin and mucosa and possibly toxic. Contact with skin causes severe irritation, redness and a burning sensation; contact with the eyes may cause severe pain, and in some cases temporary blindness for several days. Symptoms may worsen over 12 hours. If eye contact occurs, seek medical treatment immediately.

19 degrees was the low with 8 or more hours below freezing. Plants south and west positions showed no sign of freeze at all. This is much hardier than I suspected.
