Does peony like sunshine or shade?

Peony is a flower that likes sunshine. But cannot be directly irradiated during growth. If it is a potted plant, the maintenance position can be placed on the balcony and window facing east, and if it is placed in the south, it should be shaded. If it is cultivated in the field, it is necessary to choose a place with better terrain. It is afraid of strong light, so it can't be exposed to strong light, and it is easy to get sunburned.

Adequate sunshine is beneficial to its growth, but it is not resistant to summer sun. The temperature above 25℃ will make the plant dormant. The optimum flowering temperature is 17-20℃, but it must be treated at low temperature of 1- 10℃ for 2-3 months before flowering. The lowest temperature is -30℃, but appropriate cold-proof measures should be taken in winter in the northern cold area to avoid freezing injury. The high temperature and high humidity weather in the south is extremely unfavorable to the growth of peony.
