The tree was originally planted for urban landscaping and shade, but has gradually become a familiar landmark in Hanoi every summer. The purple mausoleum is also associated with the memories of many generations born and raised in Hanoi, especially at school age. The faithful purple color of the mausoleum flower and the characteristic red color of the phoenix flower have been associated with the childhood years of generations of students. As noted by the reporter of Tien Phong newspaper, these days all over the streets such as Kim Ma, Dao Tan, Tran Duy Hung, Tran Thai Tong … mausoleum flowers have begun to bloom. Just one purple mausoleum tree is enough to cool the house and help the small space on a street in Hanoi become more lively. The characteristic purple color of the mausoleum flower has created a highlight for all corners of the streets and streets of Hanoi capital. Dandelion has thick and wide foliage, so it is planted as a shade tree in many streets. The front houses in the heart of the capital are embellished with the purple color of flowers by the mausoleum to create shade, while adding to the image of a shimmering house. The flowers are purple or light purple, pinkish purple, growing in beautiful clusters. Each flower when blooming is usually spread wide and is made up of 6 thin petals, light as paper when falling to the ground. Purple lily flowers are only seen for a short time, because the flowers bloom quickly and fade very quickly. The mausoleum has many different colors such as purple, pink, light white… but perhaps the purple mausoleum is a familiar image, associated with the most memories of the people of the capital.
