Blooming begins in May and the harvesting of the plant has to be carried out prior to that in order to preserve its active principles, since as the plant flowers it loses part of its active principles.
It is original from central and middle Europe and probably from southern France. It is commonly found lengthwise the Iberian Peninsula. It grows in shaded and damp soil and in the forest; although, it is also cultivated in meadows and orchards as it is very ornamental and has a pleasant scent.
Stem with the leaves, and sometimes the flower apex.
