The birthplace of tree or shrub peonies (Paeonia arborea) is the Himalayan plateaus, where they grow in dry and rocky places. Therefore, these peonies have a deep beak root that is needed to find and absorb water from deeper soil layers. These peonies have a strong aroma. The height of the bush can reach two meters. Tree peonies should be planted in a permanent place. They are difficult, even impossible, to transplant from the fourth year, because the root is large, juicy, almost like a carrot. It breaks easily. When transplanting you will severely injure the plant and it may stop flowering for many years.
