Valeriana officinalis is a medicinal plant that also grows spontaneously, native to the Regions of Western Europe.
These are perennial shrubs, completely rustic, growing in a bush, up to 50-80 cm in diameter and 1.5-2 meters in height. The leaves are emerald green in color and have a lanceolate shape; the flowers are small, white or pink. Flowering occurs during the summer period. In its spontaneous state it grows mainly in shady areas and at the limits of wooded areas up to around 1400 meters above sea level.
This particular variety of plant generally prefers the positions of full sun or partial shade. Like all rustic plants, it resists rigid temperatures even down to -10 / -15 ° C.
The specimens of this genus withstand more easily the cold periods, compared to the very hot and muggy days, in fact they prefer the areas with mild temperatures and, above all, they love the shaded areas when the temperatures are high. In the event that this genus of plant is grown in areas with particularly cold winter temperatures, it is advisable to provide the possibility of growing these plants in pots, in order to then be able to transfer them to a protected environment.
