Plant Profile: ‘Blue Zinger’ Carex
Our busy lives mean that our landscapes and gardens often end up the last task on our giant to-do lists. This makes finding the absolutely toughest yet easiest to grow plant a high priority for most homeowners.
After I planted sedge in July and forgot to water for over a month, these plants grew! And flourished! And, well, they looked a touch tired for a while. But really, after what I put them through, who could blame them?
I have unintentionally abused and neglected this plant right from the start. Yet, it still keeps on performing well and growing beautifully.
What is this sedge that has survived and thrived when pretty much any other plant would have called it kaput within that first, hot July day?
‘Blue Zinger’ Carex (Sedge)
Definitely not the much-loathed Nutsedge. Although one can’t deny its tenacious will to live.
No. This sedge is what’s considered to be the “true sedge.” A carex. The one plant that every busy homeowner should allow to grace their landscape.

What is Carex?
Belonging to the large family Cyperaceae, there are approximately 5,500 species of sedge with more than 200 native to Missouri. One species of sedge was even used by the ancient Egyptians to make papyrus paper.
Carex is a genus of sedge that has more than 2,000 species. The Carex genus is considered to be “true sedge.”
What is the difference between a Sedge and grass?
Grass belongs to the family Poaceae and, while a sedge is certainly grass-like, the difference ends there. A sedge has solid, triangular stems whereas, Grasses have hollow stems.
Where can I plant ‘Blue Zinger’ Sedge?
While ‘Blue Zinger’ is bright enough to stand alone, the foliage color and texture also make it a phenomenal accent plant. It offers a sense of elegance yet lends itself to a more contemporary feeling.
‘Blue Zinger’ is wonderfully versatile.
The brilliant, blue-green foliage of ‘Blue Zinger’ completely leaps out of a landscape. The burst of color and texture this sedge offers is a reminder that, while flowers are much wanted, they are most definitely not needed.

‘Blue Zinger’ Carex
This sedge is mainly clump forming but will spread very slowly by rhizomes allowing it to work well planted in masses to stabilize the soil. It is somewhat more upright than the species. Blue Zinger would make an exceptional substitution to the less water-tolerant Blue Fescue.
From sun to shade, wet soil to dry soil, there is absolutely no area that this plant can’t thrive. This remarkably adaptable carex is a low maintenance sedge which requires only to be cut back in late winter before the new foliage arrives. If necessary, it can be divided in spring.
