Ranging across the Mid-Atlantic and Southern States from New Jersey to Illinois and Missouri south, Blue Wood Sedge is a striking native groundcover for shade.

Blue wood sedge is a broadleaf sedge, though the leaves are not as wide as some of the more well-known broadleaf sedges.  It grows in slowly spreading clumps 6-12 inches tall, up to 12 inches wide.  Leaves emerge bright green in the Spring, aging to a very pretty powder blue in the summer.  The color really intensifies in the fall, nicely complementing fallen autumn leaves.


Since it remains green all summer, Blue Wood Sedge makes a good groundcover for shade and woodland gardens after the spring ephemeral wildflowers have gone dormant.  Blue wood sedge grows in thick, weed-preventing clumps, though it is by no means invasive or aggressive.

Blue wood sedge is a striking replacement for the ubiquitous and overplanted Liriope often seen in shade gardens.  It is no where near as much a garden thug as Liriope, and the overall habit of blue wood sedge helps to maintain life and vibrancy in shady landscapes.

Blue wood sedge is also great for including where deer and rabbit populations are heavy - The leaves are unpalatable to these destructive herbivores.

How to Grow Blue Wood Sedge

Blue wood sedge is one of the easiest shade sedges to grow!  As long as the soil doesn't dry out excessively, it does fine.  Site in good, loose soil in shade to part sun for best effect; the foliage will bleach if exposed to too much sunlight.

Space Blue Wood Sedge 12 inches apart for a uniform groundcover, 18 inches apart for distinct clumps.  Blue wood sedge makes attractive clumps, and you can interplant the clumps with Woodland Stonecrop (Sedum ternatum) for an attractive 2-part groundcover.

We currently provide Blue Wood Sedge in Quart SuperPlugs; these will establish quickly, forming a uniform groundcover after a single growing season.
