Yellow, green, flesh red, deep red, and silver red are the top grades, especially yellow and green.

Erect type: The branches are upright and tall, with compact distribution and small expansion angle. The angle between the branch and the vertical line is mostly within 30°. The internodes are longer, and the annual growth of new branches is 10-15 cm. Generally, the height of the five-year-old plant is 40-50 cm, and the height is more than 1 meter.

Evacuation type: The branches are scattered and curved to extend around, the plant width is greater than the plant height, forming a low and unfolding plant shape, the angle between the branches and the vertical line is mostly more than 45° when the branches are unfolded, and the new branches are long and soft.

Opening type: The branches grow strong and straight, and open diagonally around, the angle is between the above two, the plant shape is perfect and correct, the height is moderate, the annual growth of new branches is 6-8 cm, and the height of the five-year-old plant is generally 30-40 cm.

Dwarf type: The branches grow slowly, the internodes are short and the leaves are dense, the branches are compact and short, the annual growth of new branches is 2-4 cm, and the height of the five-year-old plant is generally about 15 cm high.

Solitary stem type: Most of them are artificially cultivated artistic shapes, with obvious trunks, and the trunk height varies, generally 20-80 cm. There are several branches on the main trunk to form the crown (some have no crown), the shape is quaint, similar to the bonsai, the growth is slow, and the general forming period takes more than 8 years.

Peonies are the kind of plant that like sufficient light. Receiving sufficient light during the growth period is conducive to the differentiation of flower buds. If the environment is dark, it will affect the flowering of the plant. It is usually placed in a sunny place to be exposed to the sun all day, but in summer, it should be slightly shaded to prevent the leaves from losing water due to exposure to the sun, thus affecting the photosynthesis of the plant.

Peony flowers need nutrients, so fertilize them in time. Generally, organic fertilizer is used as fertilizer, which can supplement more comprehensive nutrients and will not cause fertilizer damage due to partial application. In addition, after the plant is budding, it can also play a very good role in promoting flowers by supplementing phosphorus and potassium fertilizer.
