Growing Ornamental and Flowering Grasses for Your Landscape
There are so many varieties of ornamental grasses that choosing your favorite is a challenge. Whether you prefer spring flowering grasses or those that bloom in the summer – or both – your yard can explode with color.
Growing lemongrass provides you with some fresh herbs that also repel mosquitoes.
Some grasses are tall and arching, while others are modest, some have large plums of flowers, while others have striking foliage. We’ll help you narrow your choices to find the right grass for your garden.
Are there Different Types of Ornamental Grass?
Ornamental grasses have either a spreading or clumping habit, and it’s essential to know the difference before choosing the right plants for your yard.
Clumping grass, such as little bluestem (Schizachyrium scoparium), form low mounds while spreaders, such as blue lyme grass, are tall with a dramatic appearance. Some grasses are loved for their striking foliage and others for their stunning flowers and seed heads.
Which Type of Flowering Grass Should I Grow?
There are a few things to understand when choosing your ornamental grass. There are also grasses you don’t ever want in your yard – like nutgrass and quackgrass. These invasive grasses quickly take over – usually where you don’t want them.
What kills quackgrass? Employ some DIY strategies to eradicate this unwanted weed and others.
Note that not all grasses are hardy in all growing zones. Comparing the hardiness zone of the plant to your location helps you make your selection.
It’s also important to decide whether you want to grow a clumping or spreading grass. Do you want the grass to have winter interest? Are you looking for a plant with height?
Is the ornamental grass going to be a specimen plant? Consider these questions while shopping for your new plant and read the plant care guide to find a perfect match.
What is the Difference between Cool-Season and Warm-Season Grasses?
Cool-season grass grows in early spring once the temperature is above freezing. These grasses often have vibrant color during the growing season and flower at the beginning of summer.
Warm-season grasses are slow at making an appearance in the spring and flower late in the summer into the fall months. These types of plants are heat, humidity, and drought tolerant.
Are Flowering Grasses Hard to Maintain?
Flowering grasses are tough perennials that require very little care to thrive. Most types are drought tolerant and resistant to pests such as deer. They are also not finicky about the soil, but they do require good drainage.
Let the grass sit through the winter and then trim them back in spring before new growth appears. If the grasses outgrow their space, divide them in early spring and replant the sections in a new area of the yard.
Mexican Feather Grass (Nassella tenuissima)
The thin, feather-like blades of Mexican feather grass dance gracefully in the slightest breeze. The silvery green leaves grow in early summer, with seeds at the very tips, and it bears feathery panicles all summer long.
