There are a number of ornamental grasses which can be grown for the purpose of providing good flower-or attractive of decorative value. They have been used with much success at flower shows, and there is no doubt that their presence in any arrangement does impart an air of elegance and distinction.
Many of these grasses are at their best in July, after which certain of them become less attractive. Therefore, if the spikes or plumes are required for later use, they must be secured when they are at the right stage of development. They will keep well if made up into small, loosely tied bundles and are hung upside down in an airy place or a well-ventilated. This will result in the becoming hard and rigid, and they will turn an attractive pale-golden colour.
The majority of the ornamental grasses can be treated as hardy r known as the Animated Oat, so named because their bristle-like appendages become animated by changes in weather conditions. Several of the agrostis species produce light, feathery flowers, and are sometimes known as Cloud grasses, for obvious reasons.and sown where they are to flower. They are not particular as to soil, but prefer a sunny site. Among the easily obtainable species is Avena sterilis, bette
Aira capillaris, often known as the Hair Grass, is smaller, having, from July until September, on ft stems, many hair-like branch-lets. Another dainty species is Bromus briraeformis, the Brome Grass, which has quite large, drooping spikelets.
One of the best of all ornamental grasses is Brira maxima, the quaking grass, which is invaluable both when fresh or dried for the winter. It grows 12-18 in. high, and has rather drooping stems well laden with bronze spikelets. B. minor is a smaller, daintier form.
Coix lachryma-jobi is often known as Job’s Tears, because the pearly-greyhang down as if they will fall at any moment. In the past the seeds have often been made into necklaces and rosaries.
Eragrostis maxima is the Love Grass, which produces gracefulof special use for mixing with fresh or for drying. From July until September the large branching panicles appear on 1-2-ft stems.
Hordeum jubatum is the Squirrel’s Tail. It is most popular both when fresh and dried, while it can be dyed very successfully. The Hare’s Tail grass is also much used for winter decoration, the appearance of its flower-heads giving rise to its common name.
Stipa pennala is the Feather Grass, the dainty heads, on 18-in. Stems, looking really attractive. Mention must also be made of Zea Mays, var. japonica, which is the variegated maize. There are several forms, some having narrowish leaves, while others have greater variegations. Plants of these are normally started into growth under glass in the open ground towards the end of May. The other grasses can be sown thinly in the open ground on well-prepared beds of fine soil, thebeing thinned out early so that they are able to develop into sturdy plants.
Preparing a garden to growand perennial grasses
Prepare the site forgrasses by cultivating to a fine tilth and raking in a balanced organic fertilizer at 65-100 g per sq m (2-3 oz per sq yd). A planting distance of 30 cm (1 ft) is satisfactory for most annual grasses. Water the young plants generously at first to get them established, after which one good a week in dry weather should be sufficient. Stop once the flowers and -heads appear.
Cut the heads for drying on a warm, dry day before thehas set, otherwise they will become overripe and begin to scatter. After , they are best wrapped, not too tightly, in newspaper, and hung up to dry in a warm but airy and dark place.
