Distribution of producing area

Native to the southern United States

Growth habit

Golden rooster chrysanthemum is resistant to cold and drought, lax requirements on soil, like light, but resistant to semi-shade, strong adaptability, and strong resistance to sulfur dioxide.

Reproduction

It is easy to cultivate and can often reproduce on its own. Sowing or ramet propagation are often used in production, and cutting propagation can also be carried out in summer. Sowing and propagation are generally carried out in August, and they can also be broadcast in the open field at the end of April, blossom from July to August, and blossom one after another to the middle of] October. The biennial golden chrysanthemum blossoms at the end of May and the beginning of June in early spring and lasts until the middle of October. If you want to make the golden rooster chrysanthemum blossom more, you can pick the residual flowers after flowering and chase the fertilizer once from July to August, so that the National Day can blossom.

Ornamental application

The branches and leaves are dense, especially the young leaves sprout in winter and become fresh green. Between spring and summer, the flowers are colorful and blooming all the time. Can also reproduce on its own, is an excellent sparse woodland cover. You can watch the leaves and flowers as well. The effect of covering material in roof greening is excellent, and it can also be used as flower border material.
