A complete departure from dead-nettle (Lamium maculatum), this sumptuous woodlander forms lush bushy non-invasive clumps topped in late spring by tiered whorls of showy rich purple flowers on 15-inch stems. Rarely available, it's a great one for stumping and wowing your gardening friends, and for upping your shade garden game. Divisions in deep 3.5-inch pots.
