Benefit

Use Food: Young shoots eaten as potherb. Boiling destroys irritant. Add to stews or soups. Collect the young shoots in the spring. Wear gloves while collecting shoots; the shoots can cause a stinging effect. Place young shoots in boiling, salted water (with a pair of kitchen tongs) and boil for five minutes. Serve as a vegetable or add to soups. The stinging quality disappears after cooking (Poisonous Plants of N.C.).
Use Other: Inner fibers extracted and woven into flax-like fabric by indigenous people.
Warning: Stinging hairs on all parts. Skin irritation if handled. Symptoms include intense burning and itching or stinging lasting usually less than an hour.
Attracts: Butterflies
