Why Choose Ornamental Grasses?

Ornamental grasses are a fantastic addition to any garden, offering a range of benefits that make them a popular choice among gardeners. Here are three reasons why you should consider adding ornamental grasses to your garden:

Low Maintenance

One of the biggest advantages of ornamental grasses is their low maintenance nature. Once established, these plants require minimal care, making them perfect for busy gardeners or those who prefer a more hands-off approach to gardening. Unlike many flowering plants, ornamental grasses do not require regular deadheading or pruning. They are also quite resistant to pests and diseases, further reducing the need for continual attention. With ornamental grasses, you can enjoy a beautiful garden without spending hours on upkeep.


Another reason to choose ornamental grasses is their versatility. These plants come in a wide range of sizes, shapes, and colors, allowing you to find the perfect grass to suit your garden’s specific needs. Whether you’re looking for a tall, dramatic backdrop for your flower beds or a low-growing ground cover to fill in gaps, there is an ornamental grass that will fit the bill. Additionally, ornamental grasses can be used in various garden styles, from modern and minimalist to cottage gardens and even Japanese and Zen-inspired designs.

Year-Round Interest

Ornamental grasses offer year-round interest in your garden. During the summer months, many varieties produce stunning plumes or feathery seed heads that sway gracefully in the breeze, adding movement and texture to your landscape. In the fall, the foliage often changes color, providing beautiful autumnal hues. Even in winter, when most other plants have died back, the dried seed heads and foliage of ornamental grasses can create a striking visual appeal, especially when covered in frost or snow. With ornamental grasses, you can enjoy a garden that looks beautiful and interesting throughout the entire year.

Choosing the Right Ornamental Grass

To make the most of ornamental grasses in your garden, it’s important to choose the right one for your specific conditions and preferences. Here are some key factors to consider:

Consider the Climate

Different types of ornamental grasses thrive in different climates, so it’s essential to choose a variety that is well-suited to your region. Some grasses prefer hotter climates, while others are more adaptable to cooler temperatures. Before purchasing any ornamental grass, research the specific requirements and hardiness of the plant to ensure it will flourish in your climate.

Evaluate Soil Conditions

Ornamental grasses have various soil preferences, so it’s crucial to evaluate your soil conditions before making a selection. Some grasses do well in well-drained soils, while others prefer moist or even boggy conditions. Understanding your soil’s moisture levels and fertility can help you choose a grass that will thrive in your specific garden environment.

Determine the Desired Height and Form

Ornamental grasses vary greatly in height, ranging from petite, low-growing varieties to towering giants that make a bold statement in the landscape. Consider your garden’s layout and desired aesthetic when selecting grasses of different heights. Additionally, pay attention to the grass’s general form, whether it has a clumping or spreading habit, as this can have an impact on how it fits into your overall garden design.

Popular Varieties of Ornamental Grass

There are countless varieties of ornamental grasses to choose from, but here are three popular options that are widely admired for their beauty and versatility:

Fountain Grass (Pennisetum alopecuroides)

Fountain grass is a stunning variety known for its graceful arching plumes that resemble flowing water, hence its name. This grass is available in both green and burgundy varieties, offering options to suit different color schemes. Fountain grass is a mid-sized variety, typically reaching a height of two to three feet, making it suitable for a wide range of gardens.

Maiden Grass (Miscanthus sinensis)

Maiden grass is a popular choice among gardeners for its showy, feathery plumes and attractive arching foliage. This grass can grow quite tall, with some varieties reaching heights of up to six feet or more. Maiden grass is known for its ability to provide privacy and create a stunning visual impact when planted in groups or as a focal point in the garden.

Switchgrass (Panicum virgatum)

Switchgrass is a versatile and hardy grass that comes in a variety of colors, from green to red. This grass is known for its dense clumps and elegant, upright form. Switchgrass is highly adaptable, able to grow in a wide range of soil conditions and climates. It is also a favorite among wildlife enthusiasts, as it provides an excellent habitat for birds and insects.

Planting Ornamental Grass

Once you’ve chosen the perfect ornamental grass for your garden, it’s time to plant it. Here are some steps to follow for successful planting:

Prepare the Soil

Before planting, it’s important to prepare the soil to ensure the best growing conditions for your ornamental grass. Remove any weeds or debris from the planting area and loosen the soil to improve drainage. If needed, amend the soil with organic matter to improve fertility and structure.

Sowing Seeds vs. Planting Plugs

Ornamental grasses can be started from either seeds or plugs, depending on your preference and the specific grass variety. Sowing seeds allows for more economical mass plantings and is suitable for those with patience as it can take longer to establish. Planting plugs, on the other hand, provides a more instant impact and is ideal if you want to see results more quickly.

Spacing and Depth

When planting ornamental grasses, it’s important to consider proper spacing and depth. Follow the specific instructions for your chosen grass variety, as different grasses have varying spacing requirements. Planting too closely together can result in overcrowding, while too much space can leave gaps in your garden. As for depth, the general rule of thumb is to plant at the same depth the grass was previously growing in its nursery container.

Watering and Fertilizing

Watering and fertilizing are essential components of maintaining healthy ornamental grasses. Here are some guidelines to follow:

Establishment Period

During the establishment period, which is typically the first year after planting, it’s crucial to provide regular watering to help the grasses establish a strong root system. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. This encourages the grasses’ roots to grow deeper, making them more resilient in the long run.

Regular Watering

Once established, ornamental grasses are generally quite drought-tolerant and require less watering. However, during prolonged dry spells or hot summer months, it’s still important to provide them with adequate moisture. Water deeply when necessary, ensuring the water reaches the grass’s root zone. Avoid overwatering, as excessive moisture can lead to root rot or other fungal diseases.

Selecting the Right Fertilizer

Ornamental grasses typically do not require heavy fertilization. In fact, too much nitrogen can encourage excessive leaf growth at the expense of floral display. Choose a balanced, slow-release fertilizer that is low in nitrogen to avoid overstimulating the grass’s vegetative growth. Apply the fertilizer according to the package instructions, typically in early spring, and then again in late spring or early summer if necessary.

Pruning and Maintenance

Proper pruning and maintenance are important for keeping ornamental grasses looking their best. Here are some tips to follow:

Trimming in Spring

During early spring, before new growth begins, it’s recommended to trim back your ornamental grasses to encourage fresh, healthy growth. Cut the old foliage back to a few inches above ground level, being careful not to cut into the crown of the plant. This pruning helps remove any dead or damaged foliage, allowing space for new shoots to emerge.

Dividing Mature Plants

Over time, some ornamental grasses can become overcrowded or lose their vigor. To rejuvenate them and maintain their health, it may be necessary to divide mature plants. Dividing is typically done in early spring or late fall when the grasses are dormant. Dig up the entire clump, separate it into smaller sections, and replant each division in a suitable location. This process not only revitalizes the grass but also provides an opportunity to expand your garden with additional plants.

Keeping Weeds at Bay

To ensure the best growth and appearance of your ornamental grasses, it’s important to keep weeds under control. Apply a layer of mulch around the base of the grasses to suppress weed growth and retain moisture in the soil. Regularly inspect the area around your grasses for any emerging weeds, and promptly remove them before they have a chance to compete with your plants for nutrients and space.

Dealing with Common Pests and Diseases

While ornamental grasses are generally hardy and resistant to pests and diseases, they can still fall victim to a few common issues. Here are some problems you may encounter and how to handle them:


Grasshoppers can sometimes feed on the foliage of ornamental grasses, resulting in visible damage. To prevent grasshopper damage, consider using insecticidal soaps or natural predators such as birds or praying mantises. You can also create barriers around your grasses using lightweight floating row covers to physically protect them from grasshoppers.


Aphids are small, sap-sucking insects that can infest the foliage of ornamental grasses. To control aphids, regular monitoring is essential. Hose off the aphids with water or use an insecticidal soap as needed. Ladybugs and lacewings are natural predators of aphids and can help keep their population under control.

Fungal Infections

In humid or wet conditions, ornamental grasses may be susceptible to fungal infections such as rust or powdery mildew. To prevent these diseases, ensure adequate spacing between plants to promote air circulation and reduce humidity. Avoid overhead watering, as wet foliage can contribute to fungal growth. If necessary, treat with appropriate fungicides following the manufacturer’s instructions.

Creating Beautiful Combinations

Ornamental grasses can be used to create stunning combinations in your garden. Here are some ideas for using them:

Contrasting Texture and Form

Pairing ornamental grasses with plants that have contrasting textures and forms can create an eye-catching display. For example, the fine, delicate foliage of a maiden grass can be beautifully complemented by the broad leaves of hostas or the bold, architectural presence of yuccas. Experiment with different combinations to find the perfect balance between soft and structural elements in your garden.

Colorful Pairings

Ornamental grasses are available in a variety of hues, ranging from shades of green to purples, pinks, and even reds. Pairing grasses with flowers or foliage plants in complementary or contrasting colors can create a vibrant and visually striking garden. For example, the deep purple plumes of a fountain grass can be paired with the bright oranges and yellows of marigolds or the cool blues and purples of salvia.

Blending with Perennials

Ornamental grasses work well when combined with other perennials, adding texture and movement among more static plants. They can provide a backdrop for shorter perennials or act as a unifying element throughout a garden bed. Consider planting grasses alongside daylilies, coneflowers, or black-eyed Susans for a beautiful and dynamic display.

Using Ornamental Grass in Different Garden Styles

Ornamental grasses can be used in various garden styles, adding a unique touch to each design. Here are a few examples of how grasses can be incorporated into different garden themes:

Modern and Minimalist Gardens

In modern and minimalist gardens, the clean lines and architectural form of ornamental grasses can make a striking statement. Opt for tall, upright varieties to create vertical interest, and pair them with simple, monochromatic plantings for a sleek and contemporary look. Keep the color palette minimal, focusing on different shades of green or white for a fresh and sophisticated feel.

Cottage Gardens

In cottage gardens, ornamental grasses can provide a natural and romantic feel. Choose soft, billowy grasses such as maiden grass or switchgrass to create a sense of movement and informality. Combine them with colorful perennials like roses, delphiniums, or foxgloves for a charming and cottage-like atmosphere. Be sure to leave some space for self-seeding annuals to further enhance the relaxed, carefree ambiance.

Japanese and Zen Gardens

Ornamental grasses are often featured in Japanese and Zen-inspired gardens for their calming and contemplative qualities. Opt for gracefully arching grasses such as Japanese forest grass or hakone grass to create a sense of tranquility. Combine them with other elements like water features, rocks, and moss to create a peaceful and harmonious space.

Growing Ornamental Grass in Containers

If you don’t have ample garden space or want to experiment with new design ideas, growing ornamental grasses in containers can be a great option. Here’s what you need to know:

Selecting the Right Container

Choose a container that is large enough to accommodate the specific grass variety you’ve chosen. Ensure it has drainage holes to prevent waterlogging, as excessive moisture can lead to root rot. Consider selecting a container that complements the style and aesthetic of your garden, whether it is a terracotta pot for a rustic feel or a sleek, modern planter for a contemporary look.

Potting Mix and Drainage

Fill the container with a well-draining potting mix, specifically formulated for container gardening. This will ensure the roots receive adequate oxygen and moisture without becoming waterlogged. You can also add a layer of gravel or small rocks at the bottom of the container to help improve drainage.

Watering and Fertilizing

Container-grown ornamental grasses may require more frequent watering than those planted directly in the ground. Check the moisture level of the soil regularly and water when the top inch feels dry. Avoid overwatering, as containers can be prone to waterlogging. Fertilize your container-grown grasses regularly, using a balanced slow-release fertilizer to provide them with the necessary nutrients.

With the information provided in this comprehensive guide, you’re well-equipped to choose, plant, and care for ornamental grasses in your garden. Whether you’re looking for low-maintenance plants, versatile varieties, or year-round interest, ornamental grasses offer a range of benefits that will enhance your garden’s beauty and appeal. Experiment with different grasses, combinations, and garden styles to create a stunning and unique landscape that you can enjoy throughout the seasons.
