The most common flowers in Beijing are peonies, which can be found in every place, and they are so large flowers to explore during the spring time; besides, other popular flowers are like lilacs, magnolias, tulips, and peach blossom; among them, tulips can not be found everywhere except some designated locations. Others can be found anywhere as they are excessively planted here and there. Also, different colors of roses are found almost in every road divider island, at least I found them abundantly in my living place.

Dear @tanzil2024 !
Hassan!
In East Asia, the peony was called the king of flowers.
This is because the peony was used as a medicinal ingredient in East Asia!
