The introduction into the system of sustainable agriculture is an alternative to the harvesting of medicinal plants from the spontaneous flora, ensuring the conservation of natural resources. By including in phytotherapy the active principles of the organs of this species, a qualitative leap was made. The aim was to determine the optimal planting period of the species Primula officinalis, in a experience lasting 4 years, in order to introduce it into culture. The best emergence in the following years, the plant being a perennial, had the version planted with seedlings on 28.03.2017, with an average of 7 plants, and the lowest emergence was recorded in the version planted on 10.04.2017. Analysing the influence of the planting date on the average height of the plants, it was observed that the V1 variant planted on 20.10.2016 has the highest values, with an average of 47.33 cm, the V2 variant planted on 11.11.2016 has a significant increase of 4, 00 cm compared to the control, variants V4, V5 and V6 registering negative differences. The favourable planting period proved to be autumn, in October and November, when the highest values were recorded.
