The Garden of Medicinal Plants of the Research Institute of Medicinal Plants in Plewiska (near Poznań) was founded in 1946. It was situated in the old manour park from XIX century. The garden was established by prof. Wacław Strażewicz – Nestor of Polish phytotherapy. The garden is situated on a flat surface and covers an area of 3 hectares. It is surrounded by farm buildings and fields. There is a little pond on its area. In 1980 the Garden of Medicinal Plants was admitted as a monument of culture and it was entered in a register of monuments (No 1803/A).
In the Garden 1500 taxa have been collected. Over 400 taxa were the subjects of particular research referring to acclimatization, breeding, cultivation, and phytochemistry. The research on these plants was the base for working out the new forms of plant medicines. The gathering of collection of medicinal and aromatic plants  and delivering of raw material for the futher research are the main tasks of the garden.
