🌾 Cattail (quenouille)

🔍 Identify it without mistakes

Large wetland plant growing in dense stands, instantly recognizable by its brown sausage-like flower spike at the top of a smooth, erect stem. Strap-like leaves, taller than the spike, fan out from the base. Two common species in North America: T. latifolia (male and female spikes contiguous) and T. angustifolia (a gap of bare stem separates the two parts of the spike).

1. velvety brown cylindrical flower spike
2. flat, strap-like, glaucous leaves
3. round stem without nodes
4. grows in colonies in shallow water

🍽️ Eating it

Preparation : eat the white core at the base of young shoots raw or cooked like heart of palm; boil the firm green flower spikes for 5–10 min and eat them like corn on the cob; harvest pollen by shaking the male spikes into a bag and use it to replace up to 50% of the flour in bread; mash the starch-rich rhizome (up to 70% dry matter) in water to extract the starch settling at the bottom

💊 Healing with it

use the fluffy seed heads and crushed rhizome as a poultice on burns, wounds, and insect bites (a widespread traditional use among many Indigenous nations: Ojibwe, Iroquois, Meskwaki); rhizome decoctions were used to treat diarrhea

Level of evidence : traditional use — Native American Ethnobotany Database (Moerman, University of Michigan)

⚠️ no modern clinical studies; polluted wetlands (heavy metals, agricultural runoff) contaminate the rhizome because it is a bioaccumulative plant—do not harvest downstream from pollution sources

🪓 Other bushcraft uses

• fluff from the seed heads serves as tinder and insulation (used as kapok substitute in US Navy "Mae West" life jackets during WWII)
• leaves woven into basketry, mats, and chair seats
• dried stems dipped in fat used as torches
