Stinging Nettle

Nettle Family

Urticaceae

Latin Name: Urtica dioica

Common Names: Stinging Nettle, Nettle

Native American Names: (none found)

Related Species: Along with the Nettle Family, the order Urticales also contains the Hemp, Mulberry, and Elm Family. In the Nettle Family, only the genera Dendrocnide, Laportea, Obetia, Urera, and Urtica cause contact dermatitis (1:online). Urtica ferox, New Zealand’s tree nettle, is even said to have killed a human (2:online).

Sitting With/Dreams/Sense of the Plant:

(April 19^th, 2007, Longhouse Garden Riparian Hillside, late morning, partly cloudy) While drawing this beautifully humble and delicate looking plant, memories came back of my childhood. Our backyard used to reach out into cornfields that are now covered by new development. Every year in spring a stretch of stinging nettles would sprout up between our fence and the crop. I have vague memories of climbing across the fence in my light summer dress and jumping directly into the stinging nettles, which at that time were taller than the little me. Had it not been for my parent’s lectures that stinging nettles are the reason we have beautiful peacock butterflies, I would never have been able to get over my dislike of this plant. I have learned since, that not everything that stings is bad, and while admiring it’s simple presence, I feel that through its sting, it could hold on to grace and dignity amongst human curiosity.

Botanical Description:

Habit: Herb, Perennial, Monoecious (3:371).

Fruit: small, oval, one-seed bearing, dry fruit from each flower (4:online).

Underground Parts: Extensive rhizomes, some local fibrous roots

Personal Observation and Description: Leaves can have a maroon tint when the plant is still young. While I find the plant easily confused with other plant species such as catnip (Nepata cataria), it can be distinguished by its single, straight, dark, and firm stem, hairs on its neatly opposite arranged leaves, and the height of the mature plant.

Ecology:

Habitat: Moist, rich soil in shade. Usually along streams, riverbeds, or in floodplains (5:186).

Range: Naturalized in most temperate and tropical climate zones.

Native Where: Northern Africa, temperate and tropical zones of Asia, most of Europe and North America (6:online).

Western (European-American) Uses/Relationships:

Food: Stinging nettles can be eaten when cooked. They can also be used as a coloring agent, curdling agent, and the cooking liquid used as a drink (7:online).

Personal Experience:

Food: I tasted steamed/cooked nettle on two ocasions. The first time was on March 12^th during class when someone brought in steamed nettles for their final presentation. She explained that in her native tradition nettles are celebrated as the first sign of spring and the first fresh green food of the year. The second time was during the first few weeks of Healing Gardens this quarter.

Part Used: young shoots

Procurement: I did not take part in harvesting the nettles.

Condition: fresh, cooked

Experience: Nettles have a pleasant, sublte, green taste with a touch of sourness.

Materials/Technology: (no experience)

Medicine: (no experience)

Cautions: Nettles sting! Handle with care!
