Honeysuckle of Japan - Lonicera japonica


the Lonicera japonica belongs to the Caprifoliaceae family; it is a genus of about 200 plants that includes shrubs and climbers, evergreens and deciduous plants. Some climbing species are native to China and Japan, others from southern Europe and above all from Italy. It also adapts well to living in areas with a colder climate even if the ideal climate for the plant is the mild one.
The Lonicera japonica, also known as honeysuckle of Japan, is particularly suitable for adorning walls, pergolas, fences but is also sometimes used as a hedge.


The honeysuckle of Japan prefers sunny or partial shade positions; if possible it is good to plant it in such a position that the base remains in the shade or is in any case not in direct contact with the sun's rays, while the foliage and the upper part of the plant are exposed to the sun.
The soil must be well drained and rich in humus, which must be kept moist.


the most suitable period for planting Japanese honeysuckle is April / May for evergreen species, October or March for deciduous species. If you want to make hedges with Lonicera japonica it is a good rule to maintain a distance of about 20-30 cm between one plant and another.
The leaves are oval, bright green and in some gray-blue climbing species. The flowers, which bloom, depending on the species, from spring to autumn, are tubular and gathered in groups of 2/3 flowers. These are very beautiful and very fragrant inflorescences which, in the majority of species, give way to equally ornamental berries.


The multiplication can be carried out by cutting or by sowing. In the first case, during the summer, cuttings of about 10 cm long will be taken from the stem; these must be placed in special multiplication boxes duly filled with sand and peat. In the following spring the plants will be repotted, individually, in containers with a diameter of about ten centimeters; only in autumn will they be able to be permanently installed. If the multiplication takes place by sowing, care should be taken to plant the seeds in the reproduction crates, filled with a mixture of seeds, in the autumn period. Once rooting has taken place, the plants can be transferred to individual containers with a 7/8 cm diameter; in the autumn of the following year the plants can be planted. Using this technique, you will have to wait a few years to enjoy the first flowering of the seedlings. In April and May you can cut the most "messy" branches and try to give the plant the desired shape and appearance. Furthermore, as with all climbing plants, Lonicera also requires pruning to thin out the branches and strengthen the plant itself. If used as a hedge, for the first few years it is necessary to prune the plant in half or a third of the height it has reached, in order to facilitate a more vigorous growth.

particularly dangerous for the plant and especially for its flowers are aphids, which attack the shoots and make the leaves sticky.
