This is quite possibly another microspecies and has long been in cultivation, mostly erroneously as C. buxifolia but never much more than in collections which is a shame since it is such a beautiful smaller low growing evergreen.  It forms attractive low mounds up to 1m of dark grey green foliage and is smothered in June in quite striking blossom and followed by good displays of large succulent deep blood red fruit which are usually ignored by birds.
