Description and Cultural Plant Tips

This clumping, evergreen Carex is best for creating a lush, meadow-like, natural effect.  Because it forms grass-like arching growth, it can be planted closely in clumps for a lawn substitute.  It is an excellent, very tough groundcover for shade (or sun) and is a good understory planting and happily tolerates tree root competition.  It can take traffic, both two and four-footed, and can take considerable abuse, making it a good plant for dog runs or play areas.  It doesn't require mowing but can be mowed for a more lawn-like effect or can be cut back once or twice a year to keep it fresh and tidy looking.  Can become drought tolerant but looks better with regular watering.  Can tolerate wet or boggy areas as well.

Master Gardener Comments

This Carex is happiest when planted in light shade with regular irrigation but can really stretch into many different environments.  Very versatile plant!

Propagation easy by seed or division in fall or spring.
