Description

The Creeping spurge is a striking garden perennial with its distinctive bluish foliage color, elongated stems and chartreuse flowering habit. It is a popular rock garden choice that grows into a dense mat-type plant. It brings color and texture contrast to succulents and flowering perennials in parkways, on slopes and banks, and in Southwestern and Mediterranean style plantings.

Like other species of Euphorbia, the creeping spurge is well adapted to sun and low amounts of supplemental water. Care should be taken when removing old stems to avoid contact with the milky white sap that is highly caustic to skin as well as poisonous.

Water Needs

The Creeping spurge grows well in Inland Empire gardens in areas of full sun and with low amounts of summer water. The chart shown below provides a recommended baseline guide to the monthly irrigation schedule and volume of supplemental water needed to maintain healthy growth throughout the average year. It should be noted there are several months indicated by an asterisk (*) when winter rains can provide sufficient moisture and irrigation is not needed. The high and low range of moisture indicates it can grow with varying amounts of water and you should make irrigation adjustments based on field observations of growth and character. Spring flowering is best following good winter rains; supplemental moisture will help during drought years.
