Stinging Nettle

Urtica dioica

herb

Stinging nettle (Urtica dioica) is a fast, rhizome-spreading perennial whose toothed leaves and stems are armed with tiny hollow hairs that sting on contact - a defense that vanishes the moment the leaves are cooked or dried. Beneath that sting it is one of the most nutritious wild greens: the tender spring tops are eaten like spinach, brewed into a deep-green mineral tea, and made into soups and pesto. It grows in dense colonies in rich, damp ground and spreads aggressively by creeping roots, so it is best given its own contained bed. It also hosts the caterpillars of several butterflies.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Comfrey: Another rich-soil, moisture-loving herb; both make nutrient-rich mulches and chop-and-drop feed
• Mint: Tolerates the same damp, partly shaded ground and is itself best contained, so they share a bed
• Valerian: Enjoys the same moist, fertile conditions in a tucked-away herb corner

🛡️ Pest & disease prevention

Proactive ways to stop trouble before it starts. Tap a name with an arrow for its full guide

• Aphids →

  Rinse colonies from the shoot tips; vigorous nettle usually outgrows them

• Caterpillars →

  Several butterfly larvae feed on nettle - most gardeners leave them, as the plant regrows fast and supports wildlife

• Whiteflies →

  Mainly an issue under cover; keep airflow good and rinse foliage

🌾 Harvest & storage

Harvest the top few inches of tender new growth in spring and after each cut-back, always wearing gloves and using scissors. Pick before the plant flowers, since older flowering nettle develops gritty particles (cystoliths) that are best avoided. Blanch, steam, saute, or dry the leaves immediately - cooking or drying completely neutralizes the sting - then use like spinach or for tea. Never eat the leaves raw.

🥗 Nutrition & benefits

Cooked nettle is exceptionally nutritious - very high in iron, calcium, and vitamins A and C - with a rich, deep flavor like a more intense spinach, used in soups, purees, pesto, and as a cooked green. Dried nettle also makes a mineral-rich herbal tea. All culinary use requires cooking or drying first to remove the sting.

⚠️ Toxicity & safety

Wear gloves to harvest - raw nettle stings on contact. Always cook or dry the leaves before eating, which completely removes the sting; never eat them raw.
