What is the difference between herbaceous peony flowers and tree peony flowers?

Herbaceous peony flowers and tree peony flowers - I think that if a flower enthusiast has not delved deep into this subject, they may not even be able to tell the two apart. In fact, the simplest way to distinguish them is that the herbaceous peony is a herbaceous plant, and in winter all its above-ground parts die back completely, then in the following year new shoots emerge from the base and bloom, whereas the tree peony is a woody plant, and after its leaves drop in winter it has a trunk standing upright; given enough time in cultivation it can become a tree peony tree. This is the simplest way to tell the two apart.

The other methods are shown specifically as follows

1. Leaf differences

The leaves of the tree peony are usually bipinnate with three leaflets per division; the upper surface is green and hairless, the underside is pale green and sometimes has a white bloom, and along the veins there is sparse short pubescence or it is nearly hairless. The petiole is about 5-11 cm long.

The lower leaves of the herbaceous peony are bipinnate with three leaflets per division and come in various shapes; the upper surface is yellow-green, green or dark green, and the underside is powdery green, either hairy or hairless.

2. Flower differences

The tree peony flower grows singly at the tip of a branch, about 10-17 cm in diameter, with 5 petals or double flowers, obovate in shape. Flower colors are varied, including red-purple, rose, pink and even white, and the flowering period is in May.

The herbaceous peony flower generally grows singly at the tip of the stem or in the leaf axil near the tip; the flower is somewhat smaller than the former, about 8-11 cm in diameter, with 5-13 petals, obovate in shape. Today's horticultural varieties have rich and varied flower colors, and the petals can even reach a hundred or more.
