Carex
- Description
-
Carex is a genus with over 2,000 species of grass-like perennial plants called sedges found all over the world. It is in the Cyperaceae or sedge family and is often known as true sedges. This plant has a wide variety of leaf colors and textures but the leaves are triangular in cross-section. Most species in the genus spread through rhizomes or stolens, but some species grow in tufts. The genus is divided into three main groups.
Asian- Evergreen in mild climates, usually variegated and well adapted to shade. They are suitable for containers and brighten shady corners.
New Zealand- Takes more sun, red-bronze or orange leaves common.
North American-Great lawn alternative for shady locations and restoring disturbed sites.
They are slow growing and can be more difficult to grow in a landscape setting than ornamental grasses. Sedge can handle light foot traffic. They quickly show signs of stress if they are over fertilized or over watered. Plant them along a border front, in small groups or use them in containers.
Diseases, Insect Pests, and Other Plant Problems:
Carex sedges are a hardy plant, but they can be sensitive to temperature fluctuations and soil conditions. They are also slow to recover from being cut back.
