Physical description: A cool-season, low-growing, colony-forming sedge
commonly found in open meadows and forest understories. Develops
in relatively short clusters and forms resilient, persistent
tufts resembling a lush carpet. Typically exists in extensive,
pure stands. Foliage is long, 4 to 18 inches, narrow, and fine
with stems approximately the same height. Shoots formed the previous
fall and early winter begin growth in the spring. Leaves remain
functional throughout the winter, summer, and fall. Flowering
takes place between mid-April to mid-May. The sedge produces
a reddish-brown flower that is elongated and thimble-like. Regeneration
is primarily by vegetative means utilizing cord-like rhizomes,
which are variable in length and subsist in the top 4 to 5 inches
of soil. Propagation by seed may occur, but seedlings are uncommon.
Seeds are pollinated by wind.
Optimal growing conditions: Pennsylvania sedge requires well-drained soils,
of coarse to fine texture. Exists in a wide range of soil types
from sandy loams to clay and silty clay loams, as well as alluvial
deposits. Tolerates slightly acidic and relatively infertile
soils. Grows in a wide range of landscapes and climates, but
it performs best in dry deciduous forests, grasslands, and open
areas. Winter Hardiness: Zones 3 to 8.
Susceptibility to pests and diseases:
No serious pest or disease problems
have been reported for this species.
Use:
Pennsylvania sedge provides an excellent cover for migratory
waterfowl, sandhill cranes, and ducks. It also supplies nesting
materials for ducks, sharptail grouse, and prairie chickens.
Establishes quickly in disturbed areas through vigorous production
of rhizomes. Pure stands are formed when Pennsylvania sedge invades
clearcut or burned sites. It is a strong competitor in early
stages with smaller trees and shrubs.
