A native herbaceous perennial with coarse, nettle-like leaves and stinging hairs on stems and foliage. Produces inconspicuous greenish flowers in summer and prefers rich woodland conditions.

Why grow it

Wood nettle fills a niche in woodland understory plantings where few herbaceous perennials establish reliably in deep shade and rich humus. Unlike stinging nettle (Urtica dioica), which spreads aggressively by rhizomes, wood nettle is more restrained and better suited to designed forest gardens. It serves as pioneer vegetation for disturbed woodland restoration and provides early-season forage for specialist insects.

Watch out for

The stinging hairs require careful handling during establishment and maintenance work, particularly when plants are young and tender. Wood nettle can self-seed prolifically in ideal conditions, so deadheading spent flowers may be necessary if containment is a priority. In areas with consistent moisture and rich soil, volunteer seedlings may appear beyond the intended planting zone.
