Blue Diddley® Chastetree. This new introduction from Proven Winners is a very compact version of Chastetree which makes a fun little ball of lavender-blue flower spikes in mid-summer. This selection will make a compact mound 4-6 ft. by 4 ft. It performs best in full sun but in the Deep South it might appreciate some filtered shade. Give good drainage and uniform moisture for best performance.
