Growing directions
Plant in moist, humus-rich, well-drained soil in partial to full shade, avoiding heavy clay that stays waterlogged in winter; spotted deadnettle forms a quick-spreading mat of silver-marked foliage that suppresses weeds effectively under trees and shrubs. The small pink, white, or purple flowers appear in late spring and continue sporadically through summer. Cut plants back hard in midsummer if they become leggy or stressed by heat to encourage a flush of fresh foliage. The silver-splashed leaves of popular cultivars like 'White Nancy' and 'Beacon Silver' brighten dark corners more effectively than most groundcovers. Divide every 3–4 years to maintain vigor.
