Its taproot is fleshy, stout, spindle-shaped, long cylindrical, 0.6-3.5 cm thick, yellowish brown or grayish purple.

The buds of Paeonia lactiflora are mixed buds, clustered on the root neck, fleshy, water red to light purple red, yellow and protected by scales. The length and size of buds gradually increase according to the time from pregnancy to germination.

The stems of Paeonia lactiflora are root-clustered, about 50- 1 10 cm high, herbaceous, cylindrical at the base, with horns at the upper end, some twisted and some straight, and the sunny part is mostly purple.

The leaves of Paeonia lactiflora are bipinnately compound leaves, 20-24 cm long. Leaflets are oval, narrowly ovate and needle-shaped. The leaves are long and sharp, and the whole leaves are microwave. The leaves are yellowish green, green and dark green, and the back of the leaves is mostly pink, hairy or hairless.

The flower buds of Paeonia lactiflora have several shapes, such as round peach, flat peach, flat peach, pointed peach, oblong peach, pointed peach, crooked peach, long pointed peach and almond. The outer sepals are leaflike, and the inner sepals are 3 (sometimes increased to 7), green or yellowish green, sometimes with yellow-white stripes or purple-red stripes, obovate, oval or curved.

The flowers of Paeonia lactiflora generally bloom alone at the top of the stem or near the axils of the top leaves, but there are also some rare varieties, which are actually two or three flowers with large flowers and a diameter of10-20 cm. Primitive flower, 5 outer sepals, green, 5- 10 petals, white or pink; Most stamens, 4-5 carpels, glabrous; Colors are white, yellow, green, red, purple, purple-black, mixed colors and so on.

Pattern classification characteristics of Paeonia lactiflora 1. Single flower class: Is a flower composed of a single flower?

1. 1 Melaleuca subclass: petals naturally increase centripetally, are arranged neatly, are similar in shape, and gradually decrease from outside to inside; Stamens are only inserted around the ovary and decrease with the increase of petals until they disappear. This flower is flat. ?

①? Single petal type: petals with 2-3 whorls, wide, normal stamens and pistils, usually referring to prototype. ?

②? Lotus type: 4-5 petals are round, wide and similar in shape and size, with normal stamens or individual stamens scattered in stamens to form broken petals, lanceolate petals or whisker petals; Pistil is normal. ?

③? Chrysanthemum type: petals are more than 6 rounds, gradually becoming smaller from outside to inside, stamens are normal, and the number is small; Is the pistil normal, is the number increasing or not?

Reduce. ?

④? Rose-shaped: petals increase extremely, gradually decrease from outside to inside, and stamens all disappear; The pistil is normal, degenerated into smaller or completely disappeared. ?

1.2 building subclass: outer petal width, 2 ~ 3 circles; Stamens centrifugally detached, pistils normal, valved or degenerated. Flower-shaped uplift or towering (except Jin Rui type). ?

①? Gold core type: the outer petals are wide, with 2 ~ 3 rounds, the stamens and anthers are enlarged, the filaments are thickened and the stamens are bright golden yellow; Pistil is normal. ?

②? Osmanthus type: the outer petals are wide, with 2-3 rounds, and the stamens are completely petaled into whisker petals, needle petals or lanceolate petals, which are slightly larger from outside to inside and stand upright in the outer petals; The pistil is normal or petal-shaped into tongue-shaped petals, and the color of tongue-shaped petals or the color at the end of petals is often the primary color of the stigma. ?

③? Golden ring type: the outer petals are wide, with 2-3 rounds, most of the stamens are petal-shaped, and the petal-shaped petals are towering, but a circle of normal stamens remains between the petal-shaped stamens and the outer petals; The pistil is normal or valved. ?

④? Crown type: the outer petal is wide and flat, with 2-3 rounds, and a small number of whisker-like, needle-like, needle-like or broken petals are produced in the ring beside the outer petal. The tongue-like or needle-like petals formed by stamens stand upright, protrude and cluster in the outer petal, with a small number of stamens in the center or degenerate into short petals; The pistil is normal or valved and degenerated. ?

⑤? Hydrangea type: most stamens are tongue-shaped petals, like secondary outer petals, full of flowers, like hydrangea, with few or degenerated central stamens; The pistil becomes smaller or degenerates. ?

2. Tiger: refers to the phenomenon that the center of flowers (or inflorescences) or the growing points between flowers differentiate again when plants bloom. In addition, 1 flower (upper flower) is formed in the center of the flower (lower flower), and the upper flower overlaps with the lower flower, thus increasing the degree of double petals, and some varieties even consist of 3 flowers or even 4 flowers. ?

2. 1 Melaleuca: The single flower at the base (the flower at the lower part) has the basic characteristics of Melaleuca. Melaleuca terrace type (primary terrace type): the pistil of the lower flower is normal or slightly petal-shaped; The upper flowers generally have normal pistils and stamens. The whole flower is flat. ?

2.2 Louzi subclass: the lower flower has 2-3 petals, the stamens are petaloid, and the pistils are petaloid or degenerated. All flowers are towering. ?

①? Colored petal terrace type: the pistil of the lower flower is petal-shaped, and the stamens are petal-shaped; The pistil of the upper flower is normal or slightly petal-shaped. ?

②? Layered terrace type: the pistil of the lower flower becomes the same as the normal petals, and the stamens become more petal-shaped than ③? Tapered terrace: the stamens of the lower flowers are as long and as wide as the normal petals, and the pistils become normal petals; The stamens of the upper flowers are also difficult to distinguish from the normal petals, and the pistil is petaloid or degenerated. All flowers are spherical.

There are many varieties of Paeonia lactiflora in China, and there are double-petal varieties in Jin Dynasty. Variety classification began in Song Dynasty. At that time, there were many records about Paeonia lactiflora, about 30 varieties, such as 365,438+0 species recorded in Peony Spectrum in Song Dynasty. There were 34 kinds of peony books in Yangzhou in Song Dynasty. There are 39 species of Paeonia lactiflora recorded in Xianfangpu in Ming Dynasty. In the Qing Dynasty, 88 species were recorded in "Flower Mirror". During the Qianlong period of Qing Dynasty, there were more than 65,438+000 kinds of peony in Yangzhou, including Feiyang Tuyan, Tiexianzi, Guanyin Noodle, Bingrong, Jiaohui in Today, Lianxiangbai, Rouge Dianyu and Jinziguan. In the early years of the Republic of China, a private flower garden in Shanghai claimed to have 400 varieties, including most of the varieties contained in "Flower Mirror", as well as new varieties and imported varieties bred by itself, but half of them were not officially named. Nowadays, the variety of Paeonia lactiflora in the world has developed to about 1000.

Peony has a wide range of uses, and the most important thing is to be an open-field perennial flower. Because peony has the characteristics of color, fragrance and rhyme, it is often decorated with peony in China classical gardens and planted in pieces on trees beside rockeries. Besides ground planting, Paeonia lactiflora can also be potted and used as the material of cut flowers. On the day of flowering, picking a few flowers in a bottle and keeping them in water can add luster to the house.

Normal petals are short; The stamens of the upper flowers are also petaled into short petals, and the pistils are petaled or degenerated. The whole flower has an obvious hierarchical structure. ?
