- Community: Meadows, seeps, and ditches. Grows on a
range of moist, fresh, fine textured soils. Generally does not establish
well on gravel or clay soils.
- Hydrology: Usually found in areas with season-long
saturated soils, although tolerant of a range of hydrologic regimes. It can
tolerate total inundation for up to 3 months.

small mammals and songbirds.
- Food (plants): Muskrats, geese, livestock and other
grazers. Palitability and production are high.
- Cover: Nesting waterfowl and small mammal cover.
Comments
Tolerates alkaline soils. Excellent soil stabilizer. Forms dense deep root
system with root biomasses up to 3000 g/m2 in top 20 cm of soil. Used by native
Americans for mats, bedding, and food.
Propagation and Planting
- Fruits: Achenes are lenticular, tan to brown
and approximately 1/16 of an inch long. Collect by cutting the
seedheads with a clipper. A 1/2 to 3/4 grocery bag of bulk material
will yield about 1 to 2 cups of seed.
- Propagation: Remove periygnia with sandpaper
box. Wet prechill seeds for 30 days in a mixture of distilled water
and sphagnum moss in a cooler (34 to 38 degrees F). Sprinkle seeds on top
of soils and press in to ensure seed to soil contact. Keep moist
during germination. Plants should be ready for outplanting in 2 to 3
months.
- Transplanting: This species has a rapid rate of
spread.
