From patent application:

"'NOTHOWLEE' was discovered by the inventors in April 2002 in Woodbridge, Suffolk, England. The inventors first observed 'NOTHOWLEE' as a naturally occurring single whole plant which was found by the inventors to be growing within a commercial crop of the variety of Euphorbia named 'Charam' U.S. Plant patent application Pending, Ser. No. 09/944,932, filed Aug. 31, 2001). The inventors observed that the foliage of 'NOTHOWLEE' was strikingly different from the foliage of the surrounding plants of 'Charam'. The foliage of 'NOTHOWLEE' is predominantly dark purple in coloration whereas the foliage of 'Charam' is the typical mid green for the species and hybrids of Euphorbia martinii and Euphorbia characias."

My Experience: 

I purchased a 4" pot from Thyme After Thyme in October 2009 and planted it in the Octagonal Perennial Garden. It has performed well but by spring 2012 almost all the branches were green. I purchased a second plant at Nurseries Caroliniana in May 2012 and replaced one of the conifers with it in the 'Octagonal Perennial Garden'. In the heat of the summer the old plant started to go brown. Then we had a lot of rain and both plants drooped and died. I purchased a third (and final) plant at Nurseries Caroliniana in August 2012. It lasted through August 2013 before getting too wet, I think.
