Feather Reed Grass, scientifically known as Calamagrostis x acutiflora, is a beautiful perennial grass native to central and eastern Asia. As a gardening and landscaping expert, I can confidently say that this grass is not considered invasive. While it may self-seed and spread a bit, it does so in a controlled manner and does not become overly aggressive or take over the garden.
One of the great advantages of feather reed grass is its versatility in garden design. It can be easily combined with many common taller perennials to create stunning and dynamic plant combinations. The tall, slender stems of the grass provide an elegant vertical element, while its feathery plumes add texture and movement to the garden. It is particularly effective when planted in mass or used as a focal point in a border or landscape design.
In my personal experience, I have found feather reed grass to be a reliable and low-maintenance plant. It thrives in a wide range of soil conditions, including clay and sandy soils, and is tolerant of both wet and dry conditions once established. This adaptability makes it suitable for various garden settings, from rain gardens to formal landscapes.
As with any plant, it is important to provide the right growing conditions for feather reed grass to ensure its optimal health and longevity. It prefers full sun to partial shade and benefits from regular watering during its establishment period. Once established, it is relatively drought-tolerant and can withstand some periods of dryness.
Feather reed grass does produce seeds, but it is not considered invasive. Established plants may self-seed a bit, but they do not spread aggressively or become a nuisance in the garden. If desired, you can simply remove any unwanted seedlings or thin out the clumps to maintain the desired appearance and prevent overcrowding.
To summarize, feather reed grass is a non-invasive perennial grass that adds beauty and elegance to the garden. Its versatility, adaptability, and low-maintenance nature make it a popular choice among gardeners and landscapers. While it does self-seed to some extent, it does so in a controlled manner and does not become invasive or problematic. So, feel free to incorporate this stunning grass into your garden design without any worries about invasiveness.
