Discover More Information On Korean Feather Reed Grass

The Korean feather reed grass (Calamagrostis brachytricha) will make a great addition as a specimen plant, but it also looks stunning in a mass planting. At the top of its tall stems, you will be treated to pink-tinged, feathery plumes. The plumes and foliage add dramatic movement as they catch those slightest breezes in your landscape. For a unique addition to your space, make sure to choose the Korean feather reed grass.

Plant Attributes

In the spring, you will notice a dense mound of arching linear leaves. These plants develop into attractive glossy leaves. By summer, the airy panicles will display high on the upright stems. For excellent fall interest, the Korean feather reed grass is a must-have addition. When most grasses are done for the season, this variety puts on a colorful display. The Korean feather reed grass produces pink-tinged plumes by August. When the fall season arrives, those blooms mature to a tan color. The rest of this ornamental grass transitions into a cream color near the end of autumn.

The Korean feather reed grass leaves can grow to 36 inches tall. With the plumes, it increases the height to 48 inches. At the base of the mound, the grass spreads to 15 inches in width. When the plant is in full bloom, the clump reaches 24 inches in width. Compared to other Calamagrostis varieties, the Korean feather reed grass has a more rounded and fuller growth habit.

Landscape Use

This beautiful ornamental grass looks stunning when used as a mass planting. When grouped together, the Korean feather reed grass creates an exquisite look for any landscape. The reed grass is also at home as an accent planting. With its deep roots, this variety can even provide erosion control on certain areas of your landscape.

The Korean feather reed grass is an excellent addition for a rain garden, native meadow, or shade garden. This grass will perform well in almost all garden settings, including a border near a pond or stream.

Along with the landscape uses, the plumes are often used in dried flower arrangements. The seeds of the plant provide a source of food for local birds. If you plant these varieties in your yard, you can expect to see a few feathered friends throughout the day.

Planting & Care

These plants can grow in USDA hardiness regions 4 to 9. This variety of grass is very unusual as it can thrive in the shade. However, many of the plants prefer full sun with sufficient moisture. These reed grasses can tolerate extreme summer heat and clay soils. In some cases, they may start to self-seed.

The feather reed grass must be watered well at the initial planting and throughout the first growing season. Once it has been established, they will do well with some supplemental irrigation. Until the reed grass is matured, you may not see flowers on the plant.

The flowery plumes will last until the winter snow. In the late winter, you should cut the grass to encourage new spring growth. You can prune this grass within six inches of the crown around late winter to early spring.

This reed grass variety is a low-maintenance plant. It has few problems with pests or diseases. However, you should watch out for fungal spots if you live in areas with prolonged humidity and hot weather.
