Description

Dead Nettle is an herbaceous, spreading perennial that grows up to nearly 2'. This plant blooms in late spring to early summer and is used as ground cover in woodland or shaded areas. This plant does well in dry shade where nothing else will grow. Stems root when they touch the ground, meaning this plant can become aggressive and potentially invasive or weedy if not contained. This plant is tolerant of drought, prefers full shade to partial shade, and is intolerant of full sun. Pruning to 6" will keep this plant from getting leggy. It is propagated by division in spring or by terminal spring cuttings. Plants should be spaced 12-18" apart. This plant is relatively disease free, but snails and slugs may be a problem. L. galeobdolon 'Variegatum', a cultivar, has leaves with silver variegation everywhere except on leaf margins.

Quick ID Hints:

  • Herbaceous ground cover with ovate, toothed, or notched leaves
  • Opposite silver leaves have green edges or are entirely green
  • Yellow flowers are hooded and 2-lipped, lower lip is 3-lobed
