黄秋英（scientific name：Cosmos sulphureus Cav.）is a perennial herb in the Asteraceae family, with plants about 1.5-2 metres tall and flowering in June-July each year. It has many aliases and I think it belongs to the Persian daisy family.
This flower, native to Mexico and Brazil, is mostly orange or golden yellow and is now often used as a landscape plant in my country.
The language of the flower is unrestrained, free and passionate. The sea of flowers I saw on this occasion was full of wild growth and charm.
As well as orange or golden yellow flowers, I also saw vermilion and rose-pink varieties, the bright colours of which are very appealing to people.
If you have a small yard at home, I highly recommend this flower. Plant in spring and you'll have your own sea of flowers in autumn.
