We're convinced Carex pensylvanica is not perfectly named.
More suitable might be Water Fountain Grass, but no matter what you call it, Carex pensylvanica is a stop-you-in-your-tracks soft
Sedge
that seems to sway to the rhythm of the wind.
Pennsylvania Sedge shifts with the seasons forming a carpet of peridot green in spring and turning to a sandy-golden tan in autumn.
While most ornamental Sedges grow best in
moist
or wet soil, Pennsylvania Sedge is an exception to that rule preferring dry soil and even
tolerating drought.
A
low
(6-12 inches),
clumping
perennial, it thrives in dry soil and remains lush while binding the soil with its dense roots making it perfect for
erosion control.
With its tough disposition and
spreading
habit, this
native
grass makes an excellent
semi-evergreen
groundcover that elegantly arches to the ground in a regal bow.
Fine texture and fountaining clumps make this a lovely underplanting for bolder shade perennials or on its own as a shade lawn.
Because it does well in
full sun
or
shade
and it has a restrained spreading fashion, Pennsylvania Sedge plays nicely with other plants.
Clusters of brown seed capsules cling high on the stems adding both textural and color interest in addition to a feast for hungry
birds.
Given excellent drainage and moderately moist to dry
humus-rich
soil, this plant will spread
moderately fast
and relentlessly by
rhizomes.
Depending on the soil moisture, this Sedge will spread between 3-8 inches per year and when planted in mass, the reddish-brown, thimble-like flowers and fountaining foliage create a gorgeous field-like, almost wild effect.
If you have a large empty canvas that needs low-maintenance filling with guaranteed color and texture, this Sedge is a must have.
Things to Note
Irrigation is recommended for full sun application in southern zones.
Gardener Tips
