Every country has its own flowering and harvesting seasons. Peony can grow in greenhouses and outside.
Roots get planted in autumn. During the first two years, nothing gets harvested: the plant is getting stronger in this period. After these two years, when spring temperatures are rising, the buds get bigger until they are ripe enough to get harvested. Almost everywhere in the world, the cutting gets done by hand. When a peony is given the right care, the plant can reach ten up to twenty years of age.
