After 6 years of trials, this little known but easy-to-grow selection of Euphorbia x martinii (Euphorbia characias x amygdaloides) has proven to be one of the best euphorbias we have ever grown. Honestly, I don't see any sign of Euphorbia characias in its background. Looking superficially like the wimpy, mildew-prone Euphorbia 'Chameleon', Euphorbia 'Cherokee' makes a vigorous, deer-resistant, 15" tall x 15" wide clump of dark purple stems adorned with dark purple leaves. In hot weather, the older leaves change to purple/green with only the new growth colored dark purple. In early spring, the clumps are topped with flower clusters of dark purple.
