The backward kapok characteristics of flowers, flowers fall under the tree, flowers do not wither, do not wither, and bravely bid farewell to the world. Why is kapok called "hero flower"? Because it is red but not kitsch, its thick trunk, indomitable posture and heroic grandeur, the color of flowers is as red as the backbone of a strong man and as red as the blood of a hero. Deciduous trees, up to 33 meters high. The trunk is upright and has obvious tumor thorns; Palmately compound leaves alternate with long petioles; In early spring, leaves bloom first and flowers cluster on the branches. Corolla red or orange red, about 12cm in diameter. Petals have 5 petals, fleshy, ovoid-obovate, about 9cm long, curved outward, with the edge rolled inward and star-shaped on both sides. Stamens are numerous, tubular, arranged in 3 rounds, and the outermost round generates 5 bundles; The capsule is large, woody and rectangular, reaching 15cm. It will automatically crack when it matures, and it is filled with cotton wool, which can be used as filling materials such as pillows, quilts and cross-stitch cotton. Many seeds, obovate, black and smooth, hidden in white hair. The appearance of kapok changes greatly: in spring, a tree is orange-red; In summer, green leaves are shaded; Autumn leaves are bleak; In winter, bare branches and cold trees show different customs in four seasons, which is amazing. These flowers are orange. From February to March every year, the leaves fall off and enter the flowering period, and then grow leaves. The growth environment of kapok belongs to tropical tree species, which likes high temperature and high humidity climate and has low cold tolerance. When it encounters a long-term low temperature of 5 ~ 8℃, its branches suffer from freezing injury to avoid frost. In Guangzhou, Nanning and other places in southern China, it is safe to overwinter in the open field in normal years and in cold years. In the northern part of South China and even the vast areas of North China, only potted plants can be planted, and they should be moved into greenhouses or indoors in winter, and the room temperature should not be lower than 10. The requirements for soil are not harsh. Sandy soil or clay are suitable, like acidic soil, and are more resistant to drought and water. The requirements for fertility are not very high. Generally, the soil with medium fertility and high phosphorus and potassium fertilizer has lush flowers, bright colors and sufficient water, and the soil with high nitrogen fertilizer has lush branches and leaves and many flowers, but the color is not bright. When planting, decomposed cake fertilizer or garbage should be applied as base fertilizer before and during flowering. The plant culture name of kapok originated from bonfire and Zhao Tuo, king of South Vietnam. He was named after a tree full of red flowers. Gubei originated from the transliteration of Sanskrit Karpassa; Ji Bei believes that it originated from the transliteration of Ceiba in Nanyang dialect. The name originally refers to CeibaPentandra, a kind of kapok in Java, which is confused because of its similar appearance. The name of Qiongzhi refers to the trees growing on Hainan Island, hence the name. The flowers of the kapok tree are bright red, just like the blood of a hero, so it is called the hero tree.

The flower language of kapok is to cherish the people around you, cherish the happiness in front of you, and don't regret it after you lose it, it will be too late. Kapok, a cultural symbol, is now the city flower of Guangzhou, Guangdong Province, Chongzuo, Guangxi Zhuang Autonomous Region, Panzhihua, Sichuan Province and Kaohsiung, Taiwan Province Province. The signs used by Garden Hotel, South China University of Technology, China Southern Airlines and Guangzhou TV Station all have kapok patterns, while Guangdong TV Station used kapok signs in the past. Legend has it that there is a hero of Lao Li in Wuzhishan named Hebei North, who often leads the people to defeat foreign aggression.

Once, because of a traitor's informer, the old hero was arrested, and the enemy tied him to a kapok tree and tortured him. The old hero was unyielding and was finally brutally killed. Later, the old hero became a kapok tree, so the kapok tree was called "Hebei North" to commemorate the old national hero. So how did the name of the hero tree come from? Then, look at its tree. The tall and self-supporting trunk is covered with thorns, and no one else is allowed to climb around. Branches and wheels stretch all their lives, as if to declare sovereignty to the sky. They have no leaves when they bloom, and they regenerate leaves when they are finished. It is really verve, so it is also called "Hero Tree". However, Chen Gongyin of the Qing Dynasty was the first to call kapok a hero. In his Song of Kapok, he described Kapok as "a hero with a thick beard and a big face, full of vitality and a high crown".

Since then, people have called the kapok tree a hero tree. The origin of another name of kapok is more pictographic-kapok withers and produces cotton wool, which is tied to a big tree. The cotton on the tree is called kapok. Kapok, a unique hero in southern China: the tree is tall and straight, and the wood is tough; When I was in bloom, it was red and warm, without any green leaves. Once the flowering period is over, it can't wither, but flowers can clear away heat and detoxify and give people warm care.
