The cultivation of the different varieties of the bouquets is mainly in the form and colour of flowers. Hernandez, in a book called " new spanish flora and fauna " , described the dalit plant as a single petal flower. Since 1789, when the governor of the mexican botanical gardens, vincent cerrante, transferred the dalit to the european royal botanical gardens, dalai flowers were distributed to european countries with the united kingdom as their centrepiece, and were nurtured by horticultural hybrids to produce a wide variety of purple reds, with the appearance of double petals in france and belgium, the most important link in the evolution of the dalai flower. For the first time, the heavy petal flower varieties were found to be in the municipality of count lcecur, on the outskirts of paris, where the original heavy petal flower was purple. The first discovery of a deep red ball-type flower in the nursery of j. Lee of hammersmithh in 1820, and the most popular period of the ball-type flower in 1835, when the exhibition was very popular, was an extraordinary contribution to its development and evolution. In 1836, a large embroidery with a shorter inner-clave petal was introduced, which has been in circulation for 60 years. The cactus was born in 1888 by the british breeder j. T. West. The ancestors of the decorated bouquets were of the pyramid type, and the german breeders began researching it in 1890, winning the reputation of the pyramid, which evolved into a full petal. The first flower is dark yellow and was included in the catalogue in 1900 as a large yellow flower. Small, small-scale flowers were nurtured in england by t. W. Girdlestone in 1890, and their descendants passed through the world. The early flowers are yellow and deep-skinned, growing only 20 to 40 centimetres tall, and become a well-known variety of flowers. The ring-collar varieties are said to have been first cultivated in 1890 by rivoire, a descendant of a single-capture bouquet, with significant differences in color between the rings, and were included in the great britannia catalogue in 1901. Then the stars and the orchids came to life, and other types appeared, for example, forks on the front end of the petals, or petals like feathers, which clearly show the variation of the flowers。
