Grasses are one of the families that has more plant species; these are generally plants with pleasant looking foliage and not particularly decorative flowering; however there are hybrids and crosses with foliage with unusual colors or with very pleasant flowers, useful above all for compositions of dried flowers.
Most of the plants used to prepare lawns, as well as all the cereals used for human nutrition, from barley to rice, from oats to corn belong to the grass family.
Some species are decidedly of little ornamental interest, while others can be cultivated as small shrubs, annual or perennial, and give a "wild" touch to the garden.
All grasses are tufts of thin, elongated foliage, often with a papyrus consistency; the flowers are gathered in elongated inflorescences, called spikes, which will bear the small fruits containing the seeds.
Ornamental grasses: Which species
Anyone who has a garden has grass species sown in the turf; but these small plants have a very specific purpose, so they are shaved low at regular intervals and are hardly ever observed closely. Doing so it could be noted that the grasses have some very interesting intrinsic characteristics.
First of all there are grasses suitable for any climate, they are very rustic plants, and there are species that survive the drought, as species that need abundant water and prefer almost marshy lands.
In addition, many grasses are well adapted to the European climate, so they can be resistant to frost, dry heat, snow, in short, to any weather conditions.
Most of the grass grows rapidly, without needing great care; the often stiff and papyrus leaves are not particularly attractive on the part of aphids, cochineal or cochineal.
When choosing a graminaceous plant to be placed in the garden so we only have to choose where to place it and then find the most suitable plant, for the vase, the flowerbed or even for the terrace.
First of all we consider the plants that have the best cultivation needs for the area in which we want to place them; most of the graminaceous plants are chosen for their rusticity and drought resistance, therefore in the garden we can easily find various species of cortaderia, pennisetum, fescue.
The glauca festuca for example is a perennial of small dimensions, it constitutes small tufts of rigid, arched foliage, of color tending to blue; with little or no cultivation requirements.
Other plants very present in the garden are the various species of pennisetum; the dimensions are medium, and the tufts of leaves reach the 40-70 cm of height, and in summer they produce innumerable ears of seeds, similar to small white duvets. In particular the Pennisetum setaceum rubrum has reddish spikelets, very decorative.
The cortaderia species are also highly appreciated, with large clumps of leaves and inflorescences that develop in bunches and can reach up to 150-250 cm in height, white or pink.
We also remember the species of miscanthus, some love sunny and dry climates, others need more watering, up to decidedly aquatic species.
