Roman Nettle (Urtica pilulifera) is an annual plant native to regions including Afghanistan, Albania, Algeria, and Bulgaria. It thrives in moist, light to heavy soil with a pH of 7.5–8, making it adaptable but preferring well-drained conditions. Known for its edible leaves and shoots, this nettle can grow up to 0.6 meters tall. Its presence in the Urticaceae family is marked by distinctive stinging hairs on the stems and leaves, which are a key feature distinguishing it from other plants.

Roman Nettle is a straightforward annual plant for beginners to grow, focusing on basic soil preparation and regular care.
Seeds or young plants, a container or garden bed, potting mix if using containers.
Plant in spring after the last frost, when temperatures are mild and stable.
Use well-draining soil with a pH of 7.5–8. Ensure containers have drainage holes if using them.
Direct sow seeds in the garden bed, covering them lightly. Alternatively, transplant young plants into prepared soil.
Keep the soil consistently moist and provide partial shade to help seedlings establish.
Water regularly, especially during dry spells, and mulch around the base for moisture retention. Pinch back shoots to encourage bushiness.
Prune or harvest leaves when the plant reaches 30 cm in height, cutting just above a leaf node to promote new growth.
Overwatering, planting too deep, neglecting regular pruning, and not providing enough light.
