Growth rate: It is a slow growing species

Soil and pots: It likes pots with generous drain holes, needs a very airy potting medium.

Exposure: This plant has an excellent heat tolerance and needs full sun to light shade exposures. It grows well even in full blasting sun, but can tolerate moderate shade, and a plant that has been growing in shade should be slowly hardened off before placing it in full sun as the plant will be severely scorched if moved too suddenly from shade into sun. The color of this plant is much more marked if grown in full sun.

Watering: Water regularly during the active growing season. No water should ever be allowed to stand around the roots. Keep almost completely dry in winter. However, this spurge will tolerate dryness and can even thrive in poor, dry soils, but do better when grown in nutrient-rich soils with regular watering.

Hardiness: Some cold tolerance. This spurge has tolerated temperatures down to -6ºC.
