According to the school search, in the category of true plums, plums can be roughly divided into three types according to their branches, namely straight plums, vertical plums and Longyou plums. As the name implies, the straight branch is straight plum, the natural drooping is drooping, and the curved branch is Longyou plum, which is also the best among plum blossoms. There are only two varieties, and there are few varieties of plum blossom. Youlong plum is similar to them, but there are also differences. Then, let's learn about this extremely precious Long Youmei and its aesthetics with Xiao Yisou. The crown of Longyoumei is naturally loose, forming an oblate circle for the word "Z", just like Youlong. It is precisely because of its peculiar branch state that it can enjoy both flowers and branches, which can be called a boutique in potted plants. Its branches are straight and oblique, and there are no branches without thorns. Its shoots are bright green, and half of them are dotted with dark gray, purple and brown spots, forming a zigzag shape. Long Mei, a Hui school, usually weaves by hand. Generally, Longyou plum has 1~2 flowers, and 3 flowers are also born on the middle, short and cambodia branches. There is a hole in the center of the flower bud, which is extremely shallow, fleshy, oblate and oval. Its flower shape is peculiar, butterfly-shaped, relatively flat, with four layers of petals, sparsely stacked and milky white. Petal edges are usually wavy and pedicels are short. Its sepals are generally 5-6, flat to slightly curved, and sometimes there are 2-4 membranous calyxes, which are light green and mostly covered with crimson purple. Its flowering period is between the middle of 10 and the beginning of February. Longyou plum not only has an early flowering period, but also has a short flowering period, with a single flowering period of only 8 days. Therefore, special attention should be paid to mixing with other plum blossoms when cultivating. Sister Youlong and sister Youlong are not only similar in name, but also somewhat similar in appearance. They are also a kind of plum blossom, but they are actually very different. In the plum blossom classification system, plum blossom varieties are generally divided into 3 series, 5 categories and 18 types. The three lines are mainly apricot, true plum and cherry plum. Longyou plum is one of the true plum varieties, namely "Jade petal Longyou plum". The flowers are butterfly-shaped with white compound leaves. There are few varieties, and the branches are naturally loose under the condition of natural growth, and artificial auxiliary modeling is not needed. Youlongmei is not a variety of plum blossom, but a kind of modelling technique. Choose suitable plum varieties at will and shape them, with various colors, such as red, white and pink. It is a kind of plant which is resistant to shaping and pruning and has vigorous hair growth. Trim with artificial methods such as tying palm silk and iron wire to form a strong and powerful shape, just like a flying dragon. This is a common bonsai modelling technique in gardening. This technology is not only suitable for plum blossoms, but also for osmanthus fragrans, pine needles and boxwood. It can completely satisfy people's sensory appreciation. So there are many plum blossoms in Youlong, and most of them are artificially made. Longyoumei is a rare and beautiful plant, not only because its flowers are beautiful, but also because its naturally twisted branches are like dragons, which is probably its most attractive place.
