When fresh, they added both insulation and a pleasant aroma to cover up the--frequently--muddy earthen floor. What do sedges do? Sedges have a grasslike appearance, but unlike most ornamental grasses, many perform as well or better in shade as they do in sun. Most sedges have a tufted growth habit, or they produce runners or rhizomes that create an open or slightly spreading habit. Sedges are durable and make adaptable garden companions.
What is the sedge family? How do you grow sedge grass? Requires a well-drained soil, in light to full shade. Low-growing, Plantian Leaved Sedge above combines well with other woodland plants in a naturalized groundcover. Or use it to fill-in spaces beneath shrubs and around larger plants. It's a good one for planting at the base of trees and has great fall color, too. How do sedges adapt to their environment?
Sedges have an amazing ability to survive low oxygen environments. When soil is flooded, the soil organisms consume oxygen faster than it can diffuse. Sedges have an amazing ability to grow under low oxygen conditions.
They develop air channels in their leaves, stems and roots. How bad is overfilling oil? Gardening with the RHS ». Hot links Browse inspiration articles Buy plants online. RHS Flower Shows ». Buy tickets. RHS members get reduced ticket prices Join now.

The inflorescence—or flowering part—is sometimes shaped as a collection of showy plumes, bottlebrush spikes, oat-like seed heads or silky, hair-like structures called awns. If you visit the Home Gardening Center any time from August into November, you will undoubtedly find the warm season ornamental grasses stealing the show with their billowy blooms.
One that takes almost everyone by surprise is the pink muhly grass Muhlenbergia capillaris , with airy panicles that create a rich, pink haze. For those looking to add to their gardens, the majority of ornamental grasses thrive in full sun and can handle drought magnificently.
Wet summers are a different story, though, where staking is a requisite. Because of their beautiful flowering structures, ornamental grasses are by far the most popular for gardeners, though sedges hold a special place in the hearts of those who prefer shade gardening.
Most sedges tolerate shade better than grasses and—depending on the species—they handle a wide range of soils from wet to dry. Sedges are also found worldwide, but they prefer colder, wetter regions than grasses. Rushes also thrive in colder, wetter regions and are typically found in northern regions. You can determine whether a plant is sedge, grass or rush by looking at the stems because each has a very different appearance.
If the stem is hollow it is likely a grass, as there are few grasses that have solid stems. If the stem is solid, peel the leaves back if the plant has leaves, and roll the stem between your fingers.
