About Ornamental Grasses
Ornamental grasses may be native, hybrid, suited for sun or shade, vary in height from low to incredibly tall, and come in a variety of colors and textures. Ornamental grasses are also one of the few plants that can be incorporated into the landscape that give almost year-round interest to the garden.
Ornamental grasses are categorized as either warm or cool season. Their active growth period will tell you if a grass is cool or warm season. If a grass begins to grow in late winter to early spring when conditions are damp and temps cool, the grass is a cool season grass. These grasses also flower in late spring to early summer.
Grasses that begin to grow later in the spring with most growth occurring during the warm, dry summers are warm season grasses. This type of grass likes it warm with ideal temps 80 to 95 degrees F. (27-35 C.) and will bloom in the late summer.
Grasses have many uses in the landscape. Taller varieties can stand alone or make excellent natural screens or windbreaks. Smaller grasses can be planted en masse or in small groupings with or without annual flowers. Both have their place in rock gardens, around water features, and in the native or cutting garden. Many ornamental grasses also do well in containers.
Ornamental Grasses for Oklahoma and other Southern States
There are about 10,000 species of grass accustomed to a variety of conditions which means there are likely plenty for you to choose from. They can be planted almost any time of year but ideally cool season grasses should be planted in the late summer and fall and warm season in late spring to early summer.
Before purchasing ornamental grasses in Texas or other areas of the south, take the time to identify what need you want the grass to fill. Will it be near water features, in sun or shade, container grown, used as a privacy screen, for erosion control, or for restoration? Also look to see if the grass is an annual or perennial for your region.
