Miscanthus sinensis Ferner Osten - Silvergrass

Miscanthus sinensis 'Fern Osten', also known as eulalia or Chinese reed, is a large ornamental grass, undoubtedly one of the most brilliant cultivars of its genus. This perennial forms a lush and sturdy clump, slowly but surely increasing in size. The foliage is fine, flexible, and dense. It is olive-green to greyish, with a coppery-purple sheen in autumn. The vibrant-coloured inflorescences turn silvery towards the end of the season, making the plant beautiful throughout the heart of winter, when its plumes are delicately frosted. This plant is not invasive and its inflorescences are perfect for dried bouquets. It is easy to cultivate in any ordinary soil that is not too dry but moist, in full sun.

'Fern Osten' belongs to the Poaceae family. It is a horticultural form derived from Miscanthus sinensis, native to the Far East and Oceania. This large perennial grass with short rhizomes develops into a non-running clump. It is tussock-forming. The habit is both erect and trailing, easily reaching 1.5m (5ft) in height, with a spread of at least 70cm (28in). The leaves are slender, long, and flexible. They are initially olive-green and then burgundy-copper in autumn. Long floral stems emerge from the foliage in July-August, in the form of finger-like, silky spikes 20 to 30cm (8 to 12in) long. They are an intense purple-pink, then pink when mature. As they wither, they take on a silvery hue. The plumes consist of tiny red flowers that close up shortly after, only to reopen when mature. They then take on a paler and fluffier appearance.

This eulalia has deciduous foliage, but remains decorative for much of the winter. Designed for large mass plantings, its strong presence brings grace and structure to the garden. It is also suitable for wild gardens and contemplative gardeners. Place it among asters, behind garden chrysanthemums or perpetual roses. Watch it grow and expand, play with the wind and the low autumn light, and bend under rain showers. When winter comes, it lights up the garden with its reassuring silhouette.

It has its place in modern gardens, with clean lines, alongside bamboo or ferns if the soil is moist. Miscanthus grasses are well suited for planting as a hedge, creating a screen along a path, isolating a part of the garden, or simply hiding the view of the street or a neighbour's garden. These grasses bring volume and texture to the boundaries of the garden, creating a natural transition to the open areas. They are also stunning near water features, when their majestic silhouette is reflected in the water. In an urban garden, Miscanthus 'Fern Osten' softens concrete structures. It is also possible to grow them in large containers. You can use its inflorescences to create beautiful dried flower arrangements.
