1, 2-3 rounds per petal, 10- 15 petals, wide and flat, with 200-300 stamens and 4-6 pistils. Male and female petals develop normally and have strong fruiting ability. This pattern is represented by Opium Purple, Pomegranate Red, Pearl Plate and Fontaine White. 2. Lotus petals have 4-5 rounds and 20-25 petals. Petals are wide, similar in shape and size, clearly arranged, pistil development is basically normal, and the fruiting ability is strong, but some varieties occasionally have stamens or pistil stigma petals. This pattern is represented by lotus, Jinyunhong, Saussurea involucrata and Jade Half White. 3. Chrysanthemum-shaped petals with more than 6 rounds are similar in shape, orderly arranged and distinct in layers, and gradually become smaller from outside to inside, with normal or degenerated stamens, occasional petalization, pistil 5~ 1 1, and normal growth or degeneration becomes smaller. Some varieties have petal-shaped stigma and poor knot strength. This kind of flower pattern is represented by varieties such as "Rose Red", "Laughing among the bushes", "Silver Red Clever Pair" and "Jinhong". 4. Rose-shaped petals are round, the petals gradually become smaller from outside to inside, some stamens become normal petals, the pistil degenerates into smaller or petal-shaped, and the fruiting strength is poor. This flower pattern is represented by "Purple Er Qiao", "Wuhua Yao Hui" and "Xia Hong Zheng Hui". 5. The outer petals of laurel are 2-5 rounds, which are wide and tidy. Some stamen petals become slender petals, and anthers or traces of anthers often remain in the petals. Normal stamens are mixed between petals, arranged irregularly and sparsely, and the pistil is normal or slightly petal-shaped and strong. This flower pattern is represented by "Shu Women's Dress", "Jiao Hong", "Xian 'e" and "Trilateral Saiyu". 6. The outer petals of the gold ring are 2-3 circles, wide and flat. The stamens in the center of the flower become long and narrow petals, and a circle of normal stamens between the center petal and the outer petal is a gold ring, and the pistil is normal or slightly petaloid, with poor fruiting strength. There are few such designs, such as White Swan and Hong Junyan. 7. Crown-shaped outer petals are 2-5 round, wide and flat, arranged regularly, most or all stamens are divided into finely divided or wrinkled petals, and the petals are densely raised and shaped like a crown. The inner petals are irregularly arranged, and there are often normal stamens or staminodes between petals, and anthers are often left at the ends of petals; Pistil degenerated or petaloid, occasionally bearing fruit. This flower pattern is represented by lantian jade, Hu Hong, Yao Huang and Shou Anhong. 8. Hydrangea stamens are fully petalled, with similar shapes and sizes of inner and outer petals, and crowded protrusions are spherical or oval; The pistil is basically or completely degenerated or valved, and there is no fruiting ability. This flower pattern is like "bean green", "green fragrant ball" and "snow reflecting the morning glow" 9. There are more than 4 petals in the terraced form, with neat arrangement and similar shape, and no stamens and staminodes between petals. Stamens are normally small, or occasionally petaloid, and pistils degenerate and become smaller or petaloid; The upper petals are small, spreading or erect, the stamens are getting smaller and smaller, and the pistil degenerates and becomes smaller or petal-shaped. This flower pattern is represented by Ling Hua Zhan Lu, Zhihong and Shouxinghong. 10, the stamens of the flowers are fully petaled in pavilion style, which is similar to the shape of normal petals, and the pistil petals become normal petals or colored petals; The petals of the upper flowers are slightly larger and more numerous, and the stamens are basically petaloid or degenerate; The pistil petals become normal petals or colored petals, and some varieties degenerate and disappear. This flower pattern is represented by varieties such as "Chilong Huancai", "Shengdan Furnace", "Jade House Diancui" and "Purple Paris". In the process of peony flower pattern development, some varieties often have 2-3 or more flowers on the same plant and branch. Such as "Zhao Fen", "Innocent fragrance", "White crane lying in the snow" and "blooming mountain flowers", the same plant can produce flowers such as "crown", "laurel" and "single petal". Therefore, when determining the flower pattern of a certain variety, the standard should be the flower pattern with the highest degree of evolution. Eight, the single petal flower of fruit seed bears five horns, each horn bears 7- 13 seeds, and the seeds are round. The exocarp is green and hairy at first, crab yellow when mature, yellow-green seeds, cracked fruit horns when over-ripe, and dark brown seeds, which can be called 2400-3000 dry seeds per kilogram. Double flowers generally bear 1-5 horns, but the seeds are only partially or completely fruitless; A thousand petals will not bear fruit and seeds. Identification of Peony Varieties: Peony competes with Fang Fei in spring. If you wander in the sea of flowers. Besides marveling at the beauty of this flower, I'm afraid you want to know her name. If you bring friends to see flowers, you can name one or two flowers, which will add elegance and unlimited fun. In fact, most peony flowers are not difficult to identify, as long as you have the heart to know her. Identifying flowers from flowers is one of the important basis for identifying varieties. Peony, like other flowers, is mainly characterized by its corolla, so we should look at the corolla first to distinguish varieties. Peony is divided into three types and twelve types according to flower patterns. Namely single leaf, Shuang Ye and double stage. Single petal type, lotus type, chrysanthemum type, rose type, laurel type, gold ring type, crown type, hydrangea type, chrysanthemum terrace type, rose terrace type, crown terrace type and hydrangea terrace type. Here is an example. Single petal type: petals 1-3 rounds, wide, normal pistil and pistil. Such as Huang Huakui, Splash Ink Purple, Feng Dan, Picking Fruits from the Plate, etc. Lotus-shaped: petals are 4-5 circles, wide and even, and bloom like lotus. Such as "Red Clouds and Feibei", "Tathagata Lotus" and "Cinnabar Base". Chrysanthemum-shaped: The petals are round, and the arrangement level becomes smaller from outside to inside, such as "Cai Yun", "Luoyang Red" and "Ling Hua Xiaocui". Rose-shaped: petals naturally increase, gradually decrease from the outside, and a few stamens become finely divided petals; Pistil slightly petaloid or normal. Such as "Zijin plate", "dew powder" and "big brown purple". Osmanthus type: the outer petals are obvious, wide and flat; Stamens petal-shaped, gradually tapering from outside to inside, slightly convex, hemispherical. Such as "Great Lake Red", "Lu Fen" and "lantian jade". Gold ring type: the outer petals are prominent and wide, and the middle petals are long, narrow and vertical, showing a gold ring type. Such as Zhu Sha Hong, Yao Huang and The First Case Red. Crown type: the outer petals protrude, and the middle petals are wider and wider from the center of the flower, which looks like a crown. Such as Hu Hong, Yan Rongzi and Zhao Fen. Hydrangea type: Stamens are completely petal-shaped, closely arranged and spherical. Such as "the red dragon is the color", "silver powder and gold scale" and "the sacred furnace". The latter four kinds can be summarized as pavilion: they are formed by overlapping two single flowers. Divided into "Chrysanthemum Stack", "Rose Stack", "Crown Stack" and "Hydrangea Stack". Such as "Fire Elixir", "Kunshan Night Bright", "Great Cabbage" and "Purple Paris". Peony family is famous for its eight colors: white luminous white, blue lantian jade, red alchemy, deep purple, first lattice red, mung bean green, pink Zhao Fen and yellow Yao Huang. There are also "Er Qiao" and "Jiao Rong Trilateral" with peculiar colors. In addition, the same color has different shades. In terms of fragrance type, Bai Mudan is generally fragrant, purple fragrance is relatively strong, and yellow powder has fragrance. Just "smell its fragrance and know its flowers." The leaves of Paeonia suffruticosa were identified as 3 leaves and 2 leaves. Due to different varieties, leaves show different shapes, widths, thicknesses and colors. For example, the leaves of "Dahuhong" are large, round and thick, and the leaves are mostly flat. For example, the leaves of "ink sprinkled with gold" are big and long, but the leaflets are long and narrow, thin in texture, sparsely spread or drooping. For example, the whole leaf of "Zhuangyuanhong" is medium-sized, the leaflets are oblong, the edges are short and sharp, and the leaves are inclined. For example, "Bean Green" leaves have a layer of white fluff on the back. Such as purple "big brown purple" leaves. This method of distinguishing from branches is to distinguish varieties by plant shape and branching mode. Peony is a tufted shrub, and its plant shape and branching mode are different due to different varieties. Erect type: branches with small opening angle, upright upward, long internodes, vigorous growth and high tufts, such as "Luoyang Red" and "Peach and Plum Brightening". Spreading type: the branches have a large opening angle and extend around, and the plant shape is low. Such as "Yipin Zhu Yi" and "Zhao Fen". Semi-developmental type: between the above two types, such as "Fat Red" and "lantian jade". Branching methods are divided into single branching type and cluster branching type. Single-branch type: the branches are long in the current year and there are few new buds. This kind of bud shoots in the early spring of the following year, with high plant height and sparse branches, such as "Yao Huang" and "Pink Er Qiao". Cluster type: the branches of the current year are shorter, with more new buds and strong branching. In that year, tufted short branches can be formed, and the plants are short and dense. Such as Jin Gezi and Wang Yingming and Zhu Bao. Different varieties of peony can be identified by their flower buds, and their flower buds are different in shape and color. The buds of "Luoyang Spring" are sharp and round; The buds of cinnabar thunder are narrow and sharp; The buds of "Qinglong Yan" are pointed and hooked, like the beak of an eagle. As for the bud color, it is more abundant: the bud of "Hundred Flowers Jealous" is yellow-green; The "fat red" bud is green; The buds of "Mokui" are dark purple and so on. There is a certain correlation between bud color and color. The darker the bud color, the darker the color. The lighter the bud, the lighter the color. From the fruits, it can be identified that the varieties with strong fruiting ability and open carpels are mostly single-petal and semi-double-petal varieties, such as "Jinlian" and "Feng Dan". The seed setting rate is low, and the fruits are clustered, and most of them are double-petal varieties, such as "Er Qiao" and "Zhushanlei". Distinguishing peony roots from roots is also an auxiliary means to distinguish its varieties. Some varieties have fewer capillary roots in the root system and the thickness of the roots is relatively uniform, such as "Jingezi". Other varieties have many capillary roots, which are tree-crowned. For example, the roots of most varieties of "Yingwangmingbaozhu" are white, yellow, red and white, while the roots of "Shouanhong" are purplish red, which is one of the important basis for identifying this variety.
