In recent years more and more container gardeners realise the decorative value of growing sedges and grasses amongst your container plants. The fine-looking leaves look good contrasting against smooth solid paving slopes. Raising plants up above ground level helps to display the beautiful arching shapes of some of the grasses at more of an eye-level, giving an instant impact.

Ornamental grasses and sedges comprise a wide range of shapes and sizes from the short and the broad to the tall and slender. The choice is huge.

Grasses such as Calamagrostis have slim leaves and delicate flower heads that blend into creating, naturalistic schemes. Fescues, on the other hand, are ideal for container display because of their compact nature. The flag sedge, Acorus calamus has elegant leaves and are home by the side of boggy ground near water features. So you can use grasses and sedges in different areas of the garden and you can be more adventurous.


It may seem to the untrained eye that sedges and grasses look similar but they are adapted to survive in different environments. With only a few exceptions, grasses tend to be deciduous in preferring locations in full sun and well-drained soils and composts.  Majority of sedges, on the other hand, are evergreen and can be grown in moist soil in full sun or partial shade. They can take much more growing condition than grasses.

Grasses also tend to have more dramatic flowers and seed head then sedge and therefore adding to their beauty in the garden. Grasses and sedge come into their own in winter landscapes: the leaves of the grasses tend to remain intact throughout winter, providing useful structure in border and container displays.


Popular grasses and sedges you tend to find in most UK gardens include these.  A brief description will be given here but more will be enclosed when selected varieties in each genus will be discussed further.

Tall, slim-leaved grasses such as Calamegratis  x acitofolia makes a bold statement in mixed herbaceous borders, where the gap between the leaves allow glimpses of the plants behind them.

Grasses tend to be used in prairie-style scheme for their summer foliage and flower and in winter to add some welcome structures.

Sedges, on the other hand, are used to add colour and interest to the front of beds and container displays.
