This attractive sport of 'Revolution' exhibits very dark green leaves with a medium green center. It's simply exquisite in deep shade! Quite vigorous and gets larger than 'Revolution'. Tetraploid- strong stems and thick leaves. (Don has never seen a slug hole in the leaves.)
By the way, the flowers on this one are awesome- an abundance of dark purple blooms held a foot above the foliage on nice, strong scapes.
