    Calamagrostis, also known as feather reed grass, is a popular ornamental grass known for its graceful form and feathery plumes. This comprehensive guide will provide gardeners with the essential knowledge to successfully cultivate and enjoy Calamagrostis in their gardens.

    Calamagrostis comprises around 260 species of tufted perennial grasses that primarily inhabit temperate regions worldwide. In warmer climates, they tend to grow at higher elevations. These grasses are favored for their upright structure, narrow leaves, and attractive flower/seed heads that appear later in the season. The flower heads, or inflorescences, typically emerge in mid to late summer and exhibit colors ranging from pink-bronze to pale or buff brown. They provide visual interest well into the autumn and winter. Calamagrostis may be rhizomatous (spreading through underground stems), stoloniferous (spreading through above-ground runners), or caespitose (growing in tufts or clumps). This variety in growth habits allows for flexibility in garden design and placement. Stems cut before the flowers mature will last for months in an arrangement, maintaining their golden tan color.

    Origins of the Name The name Calamagrostis originates from the Greek words 'kalamos,' meaning reed, and 'agrostis,' which refers to a type of grass. This name reflects the reed-like appearance of some Calamagrostis species and their classification within the grass family.

    Seasonal Interest Calamagrostis offers multi-season interest in the garden. The deep green foliage appears early in the spring and lasts through late fall. In colder climates, the foliage transitions to a golden tan color in winter, while in milder climates, it may remain green. The flower plumes, which emerge in mid to late summer, persist into winter, providing architectural structure and visual appeal even during the dormant season.

    Care Instructions

    • Planting For best results, plant Calamagrostis in the autumn while the ground is still warm, allowing the roots to establish before winter. However, planting can be done at any time of year, as long as the ground is not frozen or waterlogged.
    • Soil Calamagrostis thrives in moist, well-drained soil, although it can tolerate some dryness once established. It prefers a slightly acidic to neutral soil pH. For optimal growth, amend the soil with organic matter, such as well-rotted manure. If the soil is heavy clay, add grit to improve drainage.
    • Watering Newly planted Calamagrostis requires regular watering, especially during warm weather and dry spells. Once established, reduce watering frequency. In damp locations, Calamagrostis may need little to no watering. However, in free-draining soil, regular watering is necessary for the first two to three years to maintain moist but not soggy conditions.
    • Sunlight Calamagrostis flourishes in full sun, ideally receiving at least six hours of direct sunlight daily. While it can tolerate partial shade, prolonged shade may result in reduced growth and flowering.
    • Fertilizing Calamagrostis generally does not require heavy fertilization. However, in infertile soils, fertilization may be necessary to promote maximum height. A slow-release fertilizer applied in spring can be beneficial.
    • Pruning Calamagrostis requires minimal maintenance. Cut back the clumps to the ground in late winter or early spring before new growth appears. This removes old flower stems, leaves, and promotes healthy growth. Avoid cutting back in late autumn, as this would remove the attractive winter features of the plant. To maintain vigor and control size, divide large clumps in spring or fall.
    • Pests and Diseases Calamagrostis is generally resistant to pests and diseases. However, potential issues include aphids, spider mites, and fungal rust. Aphids and spider mites can be controlled with insecticidal soap. Fungal rust, which appears as discoloration on the foliage, can be prevented by ensuring good air circulation around the grass. If necessary, a fungicide can be used for treatment.

    Varieties of Calamagrostis Calamagrostis encompasses a wide range of varieties, each with unique characteristics. Some popular ones include :

    • Calamagrostis x acutiflora 'Karl Foerster' This is one of the most popular Calamagrostis varieties, known for its upright habit, early bloom time, and attractive plumes that turn golden brown in the fall. It was the first grass to receive the Perennial Plant of the Year Award in 2001, recognized for its outstanding qualities, including its versatility, adaptability, and low-maintenance nature. 'Karl Foerster' thrives in a variety of conditions and requires minimal care, making it an excellent choice for gardeners of all levels.
    • Calamagrostis brachytricha (Korean Feather Reed Grass) This variety features beautiful, airy plumes that emerge pink and fade to silver. It is characterized by its late-season bloom time, extending the visual interest of the garden into the fall. Korean Feather Reed Grass adds a touch of elegance and softness to borders and mass plantings.
    • Calamagrostis arundinacea (Reed Grass) This is a taller variety with a more relaxed form and slightly wider leaves. It provides a bolder texture and can be used as a backdrop or screen in the landscape.

    It is important to note that Calamagrostis exhibits a fascinating phenomenon known as interspecific hybridization, where different species can cross-pollinate and produce offspring with combined traits. This natural process contributes to the diversity of Calamagrostis varieties and can lead to the development of new cultivars with unique characteristics. Additionally, some species exhibit vivipary, where plantlets develop on the flower heads, and agamospermy, where seeds are produced without fertilization. These reproductive strategies further contribute to the adaptability and resilience of Calamagrostis.

    Classifying Calamagrostis can be challenging due to its similarities with other genera like Agrostis and Deyeuxia. The subtle differences between these genera require careful observation and botanical expertise to accurately identify and categorize Calamagrostis species.

    Propagating Calamagrostis The easiest way to propagate Calamagrostis is by dividing a mature clump in early spring. This method produces several smaller plants identical to the parent plant. The new plants establish quickly and may even flower in the same year.

    Uses in the Landscape Calamagrostis offers versatility in its use in the landscape. Its upright form makes it an excellent choice for adding vertical interest to gardens and borders. It can be planted en masse for a dramatic effect or used as a specimen plant to create a focal point. Due to their vigorous root systems, some Calamagrostis species can be valuable for erosion control, helping to stabilize slopes and prevent soil loss.

    Calamagrostis is a versatile and low-maintenance ornamental grass that can enhance any garden with its graceful form, feathery plumes, and multi-season interest. It is adaptable to various soil types and light conditions, making it suitable for a wide range of garden settings. Whether used as a vertical accent, a border plant, or a specimen, Calamagrostis adds texture, movement, and a touch of wildness to the landscape. With its minimal care requirements and resistance to deer and rabbits, Calamagrostis is an excellent choice for gardeners seeking an easy-to-grow and visually appealing addition to their gardens.

    When we say Calamagrostis is a cool-season grower, it refers to its growth and development cycle in relation to temperature. Here is what that means:

    • Active Growth in Cool Temperatures: Cool-season grasses, like Calamagrostis, start growing actively in early spring when temperatures are still relatively cool (around 40-75°F or 4-24°C). They continue to grow well through spring and into early summer.
    • Slow Growth in Summer Heat: As temperatures rise in mid-summer, their growth rate slows down. They might even go partially dormant during periods of intense heat or drought.
    • Rejuvenation in Fall: With the cooler temperatures of fall, cool-season grasses experience a renewed period of active growth.

    What this means for gardeners:

    • Early Spring Emergence: You will see Calamagrostis green up and start growing early in the spring, often before many other plants.
    • Early Bloom Time: Cool-season Calamagrostis varieties like 'Karl Foerster' tend to bloom earlier in the summer compared to warm-season grasses.
    • Fall Interest: They often retain their green color or develop attractive fall foliage colors as temperatures cool down.
    • Planting Time: The best times to plant cool-season Calamagrostis are in spring or early fall when temperatures are moderate.

    Contrast with Warm-Season Grasses:

    Warm-season grasses, on the other hand, thrive in warmer temperatures (75-95°F or 24-35°C) and go dormant in winter. Examples include Big Bluestem (Andropogon gerardii) and Switchgrass (Panicum virgatum).

    Understanding the growth cycle of cool-season grasses like Calamagrostis helps you choose the right plants for your climate and garden conditions and allows you to provide the best care for them throughout the year.

    Caring for Calamagrostis in your garden is relatively easy, as they are generally low-maintenance plants. Here is a breakdown of the key aspects:

    Fertilizing:

    • Fertilize once in spring with a balanced fertilizer following the package instructions. Avoid over-fertilizing, as it can encourage excessive growth and weaken the plant.

    Pruning:

    • The main pruning happens in late winter or early spring before new growth emerges.
    • Cut back the entire plant to the ground, removing the dead flower stalks and foliage. This encourages fresh, new growth and maintains the tidy appearance of the plant.

    Additional Care:

    • Dividing: If your Calamagrostis becomes too large, you can divide it in spring or fall. Dig up the clump, carefully separate the divisions, and replant them in suitable locations.
    • Staking: Some taller varieties, especially in exposed areas, might benefit from staking in early spring to prevent them from falling over.
    • Pests and diseases: Calamagrostis are generally resistant to pests and diseases. However, keep an eye out for common grass problems like aphids or rust, and treat them promptly if necessary.

    By following these simple tips, you can ensure your Calamagrostis thrives and adds its unique beauty to your garden for many years to come. Remember, the specific needs of your plant might vary slightly depending on the variety you have and your local climate. So, observe your Calamagrostis and adjust your care accordingly for optimal results.

    No, Calamagrostis plants are not considered to be particularly attractive to pollinators like bees, butterflies, or hummingbirds. This is because their flowers are small, inconspicuous, and lack the nectar or pollen rewards that pollinators typically seek.

    The feathery plumes of Calamagrostis, while aesthetically pleasing, do not offer much in terms of sustenance for pollinators. Additionally, the timing of their bloom period often coincides with the abundance of other, more pollinator-friendly flowers, making Calamagrostis less competitive for pollinator attention.

    However, Calamagrostis can still play a role in supporting healthy pollinator populations by providing:

    • Habitat and shelter: The dense clumps of Calamagrostis can provide shelter and nesting sites for some pollinator species, such as ground-nesting bees and butterflies.
    • Food source for other insects: While not directly attractive to pollinators, Calamagrostis can support populations of other insects that pollinators prey on, indirectly contributing to the food web.
    • Aesthetic value: By creating an attractive and diverse garden with a variety of plants, including both pollinator-friendly and non-pollinator-friendly ones, you can help to create a welcoming environment for all types of wildlife, including pollinators.

    So, while Calamagrostis may not be a magnet for bees and butterflies, they can still be a valuable addition to a pollinator-friendly garden by providing habitat, shelter, and contributing to the overall biodiversity of the ecosystem.

    Fortunately, Calamagrostis are generally quite resistant to pests and diseases, making them relatively low-maintenance plants. However, there are a few occasional issues to keep an eye out for:

    • Provides enough time for roots to establish before winter, but the plant will have less time to recover before the following growing season.
    • Divide in early fall, at least 6-8 weeks before the first frost.
    • Large clumps can be divided in fall with a good chance of flowering the following spring, while smaller divisions might require another season to reach full bloom.

    Here are some additional factors to consider when deciding when to divide Calamagrostis:

    • Plant size and health: Dividing overgrown or congested clumps is beneficial for revitalizing the plant. However, avoid dividing small or weak plants, as they might struggle to recover.
    • Local climate: If you have harsh winters, dividing in spring might be safer to ensure the new divisions have enough time to establish before the cold weather arrives.
    • Specific species: Some species, like Calamagrostis x acutiflora 'Karl Foerster', can be divided in either spring or fall with good results. Research the specific needs of your Calamagrostis variety.

    Remember, regardless of the timing, proper division techniques are crucial for the success of the process. Ensure you have sharp tools, prepare the new planting locations, and water the divisions thoroughly after planting.
