Evergreen hedge plants
Evergreen hedge plants are among the most widespread to create very dense and compact structures that do not lose their foliage during the cold season. Using evergreen shrubs, the hedge maintains its continuity throughout the year, without the need for further screening. Even when one intends to prepare a mixed border, many of the specimens planted are evergreen, so that the purpose of decorating the garden is perpetuated even in winter. On the one hand, part of the cleaning work is avoided: the deciduous varieties lose all the foliage upon the arrival of the autumn cold, forcing a heavy job of collecting the dry leaves. Evergreen varieties always lose a few leaves, immediately replacing them with new organs; it will be sufficient to pass the rake to the base of the shrubs, periodically in order to remove the fallen leaves.
What plants to choose
Since the evergreen hedge plants are among the most used, in the nursery many are available, suitable to satisfy every taste and desire. Typical varieties with bright green foliage, such as prunus laurocerasus, laurel, pittosporum, viburnum, boxwood or various conifers and resinous; for those who want a little more color, which gives brilliance to the garden, there are also types in colored varieties, such as the red leaves of the photinia x fraseri, or the various colored leaves of white and yellow of the letterhead or of ornamental hollies. If you also want winter berries, you can plant the pyracantha, an easy-growing, fast-growing plant that produces beautiful orange, red or yellow ornamental berries. The choice depends very much on personal tastes, but also on needs: boxwood is preferred for medium or small hedges, while prunus laurocerasus produces hedges that quickly exceed two meters in height.
Place the plants of the hedge
To have a thick and compact hedge it is good to cultivate the shrubs that compose it; always choose healthy and robust specimens, because the time of transplantation is very delicate, and the risks that a plant already sickly suffers are excessive. If you want the hedge to perform its functions in part, choose shrubs that exceed 50-6 'cm in height; if you want to save money, buy them smaller, but don't place them too leaning, because otherwise you will have to eradicate some of them over time. Before planting the chosen varieties, work the soil well, in order to enrich it with manure, and also to lighten it with sand or peat, to make it well draining and permeable to water. Once the shrubs are in place, compact the soil with your foot or shovel, and water well.
The flowering plants
Green varieties are often opposed to flowering plants; although many of the most striking flower varieties present deciduous foliage, there are many evergreen shrubs, which also have the merit of producing a decorative flowering. One of the most typical shrubs is the oleander, which has beautiful evergreen lanceolate leaves, dark in color, and in summer it is filled with colorful flowers. But most perennial species also produce a beautiful flowering, a pity that often occurs at the end of winter, and that with the pruning work done in advance, most small flowers tend to be removed. If you want to enjoy the bloom of your photinia or pyracantha, prune them late in the spring, after they have produced their countless white flowers. There are also some unexpected jewels, which produce not particularly decorative flowers, but with a heady scent; a classic example is the osmanthus, a vigorous shrub, which in autumn produces small white flowers, difficult to see, but which are barely felt because of their incredible aroma.
