What is Diamond Grass?

Diamond grass, botanically known as Calamagrostis brachytricha, is one of the most graceful grasses you can plant in a garden. This beautiful Asian ornamental grass forms a compact clump of fresh green leaves that arch elegantly outwards. In late summer, its characteristic full plumes appear, immediately drawing the eye. The plant owes the name 'Diamond Grass' to the fact that the plumes hold dew and rainwater in a unique way, making the plant look as if it is encrusted with countless sparkling diamonds in the morning sun. At Planten247, we often recommend this grass to customers looking for a plant that adds both structure and a dreamy atmosphere to the border.

The benefits of Diamond Grass?

Planting Calamagrostis brachytricha brings many benefits to your outdoor space. The main advantages of this ornamental grass are:

• Unique ornamental value: The plumes catch moisture and create a beautiful shimmering effect in the garden.
• Autumn color: The green foliage turns warm, golden-yellow hues in the fall before going dormant.
• Winter appearance: Even after the plant has finished flowering, the silhouette remains a beautiful, natural decoration throughout the winter.
• Non-invasive: This grass grows in neat clumps and will not spread unwantedly throughout the garden.
• Low maintenance: Apart from an annual pruning in early spring, the plant requires hardly any attention.

What to look for when buying Diamond Grass?

When buying Diamond Grass, it is important to pay attention to the vitality of the root ball and the sturdiness of the stems. A healthy Calamagrostis brachytricha should have a well-developed root system in the pot, allowing the plant to quickly establish itself in your garden soil after delivery. At Planten247, we ensure that every grass is carefully checked for quality before it is shipped. Also, make sure to choose a location where the plant has enough space to display its natural, arching growth habit without being crowded out by neighboring plants.

Diamond Grass Hardiness

Diamond Grass is extremely hardy and can effortlessly withstand temperatures well below freezing. It is a robust plant that is not sensitive to Dutch frost periods, provided the soil does not remain extremely wet in winter. Although the foliage withers and dies back in winter, the plant itself remains perfectly healthy underground. The dry silhouette of the clumps and plumes protects the heart of the plant against the coldest days while simultaneously providing a shelter for small insects in the garden.

Planting Diamond Grass

Planting Diamond Grass is a simple process that yields the best results in well-drained, humus-rich soil. Dig a spacious planting hole and mix the soil with some planting compost to promote a good start. Place the root ball in the hole and ensure that the top of the root ball is level with the ground surface. Water generously immediately after planting so that the roots make good contact with the soil. For a beautiful dense effect in a border, we recommend placing about 3 to 5 plants per square meter.

How should you maintain Diamond Grass?

Maintaining Diamond Grass is a piece of cake and takes very little time. The most important moment is early spring, just before the new shoots emerge from the ground; at that point, cut back the old, withered stems and leaves to about 10 centimeters above the ground. During a very dry summer, it is advisable to give the plant some extra water occasionally, especially if it is in full sun. An annual modest fertilization with organic granules in the spring stimulates growth and ensures an extra rich flowering of the beautiful plumes.

Combining Diamond Grass

Diamond Grass combines beautifully with various perennials and other ornamental grasses in the border. Its natural appearance provides a great contrast to colorful late bloomers such as Coneflower (Echinacea), Stonecrop (Sedum), or the Michaelmas daisy. Calamagrostis brachytricha also comes into its own in combination with other grasses with a finer structure. Because of its average height, it is an ideal plant for the middle layer of a border, with the plumes protruding beautifully above lower ground covers.

Frequently asked questions about Diamond Grass

Is Diamond Grass poisonous?

No, Diamond Grass (Calamagrostis brachytricha) is known as a non-toxic plant. This makes it a very safe choice for families with children and pets. For humans, there is no danger from touching or accidental ingestion, although the plant is not intended for consumption. It is also harmless to dogs and cats; if they happen to nibble on it, it will not lead to signs of poisoning. However, the leaf edges of ornamental grasses can sometimes be sharp, which can cause irritation in the mouth or throat if a pet eats large quantities of it, but the plant itself contains no toxic substances.

Is Diamond Grass a perennial?

Yes, Diamond Grass is a perennial plant in the ornamental grass category. This means that the plant sprouts again every year and becomes slightly more robust and fuller each time. Although the above-ground parts die off in winter, the base of the plant remains alive. You are therefore investing in a plant that you will enjoy in your garden design for many years to come.

Is Calamagrostis evergreen?

No, Calamagrostis brachytricha is not evergreen. In the autumn, the foliage turns yellow and brown, after which it withers. Although the grass does not remain green, it does retain its structure throughout the winter. This 'winter appearance' is very decorative, especially when there is a layer of frost or snow on the old plumes and leaves, which creates a beautiful winter scene.

How tall does Diamond Grass get?

Diamond Grass typically reaches a height of about 80 to 100 centimeters when the plant is in full bloom. The foliage itself forms a clump of approximately 50 to 60 centimeters high, after which the flowering stems with the plumes grow majestically above it. Because of this height, it is a very versatile plant that finds a suitable spot in almost every garden, from a small city garden to a large rural border.

What location is best for growing Diamond Grass?

Diamond Grass is a flexible plant, but it blooms most profusely in a sunny to semi-shaded spot. Unlike many other ornamental grasses that only want to be in full sun, Calamagrostis brachytricha also does surprisingly well in places with slightly less direct light. A location with filtered sunlight is often ideal for admiring the dew drops on the plumes for as long as possible before they evaporate.

When exactly does Diamond Grass bloom?

The flowering period of Diamond Grass usually starts in August and continues until October. The plumes first appear in a greenish tint and turn a warmer, straw-like color as the season progresses. Especially in late summer, when many other plants have passed their prime, this grass provides a fresh impulse and renewed beauty in the garden.

Can Diamond Grass also be kept in a pot on the terrace?

Absolutely, Diamond Grass is perfectly suited for use in a spacious pot or planter. Provide a pot with holes at the bottom for drainage and use high-quality potting soil. Because the roots have limited space in a pot, it is important to water the plant regularly during the summer months. This way, you can enjoy the sparkling plumes of this special grass on a balcony or terrace as well.
