Korean feather reed grass

Product Image
A useful, clump-forming, upright grass that will thrive in sun and partial shade, this is grown for its tall, fluffy flower heads that are silvery-grey with pinkish-purple tints.

Creating a gently arching fountain of grey-green foliage, which takes on buttery shades in autumn. The emerging growth can be a bit tatty, so place it in the middle of the border. Its best planted in full sun as it tends to flop over more in shade.

Calamagrostis brachytricha has been given the Award of Garden Merit by the Royal Horticultural Society.

How to care for Calamagrostis brachytricha:

Calamagrostis is a hardy, low-maintenance ornamental grass that thrives in full sun and well-drained soil. When planting, work some organic matter, such as well-rotted compost, into the soil to improve drainage and nutrient content.

Space the plants about 60-90cm (2-3ft) apart to allow for their upright growth habit. After planting, water regularly until established. Once settled, this grass is moderately drought-tolerant and requires minimal watering.

In February, cut the stems down to ground level to encourage fresh growth in spring (avoid cutting earlier, as the tall, wheat-coloured stems provide striking visual interest and structural presence in the winter garden). Applying a layer of mulch in spring will help retain moisture and suppress weeds.
