Euphorbia x martinii 'Ascot Rainbow' PP 21,401 (Ascot Rainbow Spurge) - An compact moderately short lived perennial that grows 24 to 30 inches tall by 20 to 24 inches wide with very distinctly variegated narrow 2 inch long leaves that are displayed as neatly-layered rosettes rising up on the many stems from the base of the plant. The foliage and lower flower bracts are a rich blue-green color edged with yellow-cream that dramatically flushes red with new growth in spring and again as temperatures cool in the fall and then holding this color through winter in our southern California gardens. The flowers which rise up just above the foliage in mid to late spring and last into summer have clusters of the typical compound euphorbia flowers, called cyathiums, which have chartreuse and yellow bracts with dark red staminate flowers at the base of the cup-like involucres. Plant in full sun in a well-drained soils and give moderate to occasional irrigation. Hardy to at least -10°F - it is doing well in gardens in USDA Zone 6 and being tested in Zone 5. It is quite pest free and not attractive to deer or rabbits. Remove any reverted non-variegated stems and cut down to ground older stems in summer after new shoots have risen up 6 inches of more. Reliably lives for two to four years in most gardens and reportedly its performs best in the cooler Pacific northwest. It is useful as a container specimen, in the border or mixed with grasses as an accent in a meadow like setting. This plant is the result of the selection of a naturally occurring branch sport of an unpatented cultivar of Euphorbia.x.martinii (E. charachias x E. amygdaloides 'Rubra') that was discovered by David Glenn of Lambley Nursery in Ascot, Victoria Australia in 2005. It is similar to Euphorbia Helena's Blush but has a broader variegation and deeper red winter coloration. E. 'Ascot Rainbow' was winner of the Bronze Medal at the 2010 Plantarium and received its US Plant Patent on October 19, 2010. It is marketed in the US by PlantHaven.
