Carex pensylvanica Sedge, or Carex, is a family of compact, mounded to low-arching ornamental grasses that establish extremely well in shady gardens and containers. They also tolerate clay, moist to well-drained soils, and even some drier conditions. There are many colorful varieties with yellow, green and white variegation on thin to narrow and wider strap-like leaves. 'Pennsylvania' offers narrow, low-growing foliage that forms a lush green carpet and makes for a good alternative to the traditional lawn or ground cover. It spreads slowly by rhizomes and is most effective when planted en masse. Grow in part shade to shady areas, well-drained or evenly moist amended soil or containers. Feed with a slow release fertilizer, Osmocote® or Plant-tone®. Follow label instructions. Cut back in early spring as low as possible. Mulch 2" to suppress weeds, retain moisture and protect against extremes of soil temperature.
