Sedge is a grass-like plant that sways in the wind and pairs nicely with coarse-texture plants like hostas. This tough and versatile plant acts as a groundcover, filling in around other perennials and eliminating the need for mulch. Sedge provides shelter and food for small animals and pollinators.
Garden Plans For Sedge
Sedge grows in silvers, soft blues, golds, reds, and everything in between—even an attractive brownish bronze. Many of the straight species of sedge are a light green color, which works well as a backdrop plant. Along with the attractive foliage, many sedge have small, spiny seed heads lending even more textural interest.
Sedge Care Must-Knows
Sedge is one of the largest groups of plants with close to 2,000 species. Sedges can be found in almost every part of the world, thriving in different growing conditions. You can find sedge for sun or shade and for dry or moist conditions. Read the plant tag to make sure the sedge you pick will succeed in your garden climate.
Many of the native sedges growing in the United States are great for filling in between other plants, because they can be fairly vigorous spreaders by underground rhizomes. Other types are clump-forming and will stay put no matter where they are. Creeping types can easily be divided as needed to help fill in a garden space. If your sedge begins to look a little ragged, cut it back and allow it to regrow. Keep in mind that they tend to be slower growing than grasses, so only cut them back if absolutely necessary.
Sedges generally like evenly moist soil. There are some that handle droughts well, but overall they will slowly decline in dry conditions. One thing most sedges won't tolerate is wet soil. Water-logged soil can cause sedges to rot. Be consistent with your watering, whether it's on the dry side or the wet side, because sedges can become stressed from constant fluctuations of moisture.
In recent years there have been many noteworthy introductions. The Evercolor series is a group of Asian sedges that grow well in containers or as a pop of color in a shady garden. New varieties tend to feature beautifully colored variegated foliage that is evergreen in mild climates and requires very little maintenance to look good.

This plant hardly grown 40 years ago is now one of the most commonly grown garden plants. But hosta has earned its spot in the hearts of gardeners -- it's among the easiest plants to grow, as long as you have some shade and ample rainfall.Hostas vary from tiny plants suitable for troughs or rock gardens to massive 4-foot clumps with heart-shape leaves almost 2 feet long that can be puckered, wavy-edged, white or green variegated, blue-gray, chartreuse, emerald-edged -- the variations are virtually endless. Hostas in new sizes and touting new foliage features seem to appear each year. This tough, shade-loving perennial, also known as plaintain lily, blooms with white or purplish lavender funnel-shape or flared flowers in summer. Some are intensely fragrant. Hostas are a favorite of slug and deer.
Named for the Greek goddess of the rainbow, iris indeed comes in a rainbow of colors and in many heights. All have the classic, impossibly intricate flowers. The flowers are constructed with three upright "standard" petals and three drooping "fall" petals, which are often different colors. The falls may be "bearded" or not. Some cultivars bloom a second time in late summer. Some species prefer alkaline soil while others prefer acidic soil.Shown above: Immortality iris
