Tall Ornamental Grass

What are the best-known and most popular tall ornamental grasses?

Among the true giants in the garden, tall ornamental grass is indispensable for those who appreciate a natural look. The most iconic species is Silver Grass (Miscanthus sinensis), which comes in many varieties and easily reaches heights of two meters. Feather Reed Grass (Calamagrostis acutiflora 'Karl Foerster') is also an absolute winner; this tall ornamental grass is known for its sleek, vertical growth that remains upright even in strong winds. For a more transparent effect, Feathered Grass (Stipa gigantea) is very popular, with its golden-yellow plumes rising high above the foliage. These species are so popular because they build up an impressive volume in the garden in a short time.

The benefits of tall ornamental grass?

The greatest advantage of a tall ornamental grass is its versatility. They function excellently as natural garden dividers or screens, allowing you to create more privacy without having to install a solid fence. Additionally, tall ornamental grass adds dynamism; the stems rustle softly in the wind and catch the light in a beautiful way. In winter, these grasses offer a stunning silhouette, especially when a layer of frost lies on the plumes. Another advantage is the structure; they form the perfect backdrop for lower perennials, giving your garden a layered and professionally designed look.

What to look for when buying tall ornamental grass?

When choosing the right tall ornamental grass for your border, there are a few important factors:

• Final height: Pay close attention to the maximum height; Some species remain around 1.5 meters, while others exceed 2.5 meters.
• Growth habit: Are you looking for a compact, vertical grower or a species that spreads out widely?
• Location: Most tall grasses need plenty of sunlight to develop their sturdy stems.
• Transparency: Some grasses form a dense wall, while you can still subtly see through other species (such as Molinia).

What types of tall ornamental grass are there?

There is a great variety within the category of tall ornamental grasses. You have the robust Miscanthus varieties that often form large flower plumes in late summer. In addition, there are the 'tight-cut' grasses such as Calamagrostis, which are ideal for narrow strips or modern gardens. Purple Moor Grass (Molinia caerulea 'Arundinacea') also belongs in this list; this tall ornamental grass has relatively low foliage, but sends its flower stalks up to two meters into the air. Whether you want a dense green wall or an airy, swaying accent, there is always a tall grass that fits the scale of your garden project.

What are good evergreen tall ornamental grasses?

Are you looking for a tall ornamental grass that retains its structure and color even in winter? Although many tall grasses turn straw-yellow in winter, there are a few rock-solid exceptions that remain green year-round. The Carex pendula (Convolving Sedge) is an absolute winner; This plant forms large, impressive clumps with gracefully overhanging foliage that remains beautifully green even during frost. In addition, Luzula sylvatica (Great Woodrush) is a reliable choice that can grow up to 80 centimeters tall and forms a dense, evergreen carpet. For a sleek, vertical look, Sesleria autumnalis is highly suitable; this grass remains vital and fresh during mild winters. With these evergreen giants, you enjoy natural privacy and a vibrant, green border all year round. How and where do I plant my tall ornamental grass? The ideal spot for a tall ornamental grass is at the back of the border or as a solitary plant in a large lawn. They need space to display their full size. Preferably plant them in a sunny to semi-shady spot with nutritious, well-draining soil. When planting tall ornamental grass, it is advisable to dig a spacious planting hole and enrich the soil with compost. Give them sufficient water during the first period after planting so that they can develop a deep root system. Is the grass located in a very wind-sensitive spot? Then choose varieties with extra sturdy stems to prevent them from blowing over.

How do I care for my tall ornamental grass?

Caring for tall ornamental grass is surprisingly simple. The most important thing is the annual pruning in early spring (March). Cut back the dead stems from the previous season to about 10 to 20 centimeters above the ground, just before the new shoots appear. Be sure to leave the grass standing during the winter; the withered stems protect the plant from frost and are very decorative. An annual application of organic fertilizer in the spring stimulates growth, allowing your tall ornamental grass to reach its full height again in just a few months. With very large clumps, you can 'divide' (split) the plant after a few years to rejuvenate it.

Frequently asked questions about tall ornamental grass

When does tall ornamental grass reach its maximum height?

Most varieties of tall ornamental grass reach their full height during the summer (July/August). Because you cut them back short in the spring, they undergo an impressive growth spurt every year, sometimes reaching as much as 150 to 200 centimeters in a single season.

Are tall ornamental grasses suitable as a boundary fence?

Absolutely! A dense variety like Miscanthus is perfect as a natural divider. However, keep in mind that these grasses die back above ground in the winter and are cut back short in early spring. During that period (March to May), you will therefore have temporarily less privacy until the grass has grown back.

Do tall ornamental grasses spread?

The varieties in the Planten247 range are 'clump-forming'. This means that they stay in place and become slightly wider each year, but do not produce underground runners that spread throughout the garden. So you don't need to worry about unwanted spread.

Is tall ornamental grass winter hardy?

Certainly, most tall ornamental grasses are very winter hardy. Although they turn straw-colored in winter, the roots survive severe frost without any problems. It is actually best to wait until spring to prune them, because the old stems protect the plant from the inside against cold and moisture.
