The Mediterranean spurge is a show-stopper during the late winter to early spring when the winter rains provide moisture for robust growth and flowering. The combination of blue-green foliage and chartreuse flower bracts achieve the appearance of giant puff-balls in the garden. No other plant achieves this unique color and character combination.

The Mediterranean spurge can be grown throughout the Inland Empire and is often planted in parkways, on banks and in mixed plantings. The herbaceous stems die after flowering and need to be removed; new stems already start their growth in early spring to replace the old stems. Care needs to be taken to avoid contact with the milky sap that is highly caustic to the skin and also poisonous. One subspecies, E. c. 'Wulfenii', grows 3-4 ft. tall and as wide in a round mound and produces the largest clusters of flower bracts.

Water Needs

The Mediterranean spurge and its several cultivars all grow 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.

Dead-head after flowering by removing entire flowering stem, usually in late summer (D). When pruning any Euphorbia, always wear eye protection and gloves, and avoid contact with the highly irritating white sap. If it gets on you, wash it off immediately (S).
