Gardenia jasminoides Ellis is a small evergreen tree or shrub of Rubiaceae. Originally from China, it is distributed in tropical and subtropical areas such as China, Japanese and Vietnamese. Often do garden flowers and plants. The plant height of Huang Zhi is about1~ 2m, and the leaves are opposite, obovate, with triangular stipules, opposite to thorns. Flowers are terminal, with double petals and single petals (six petals). Double petals are like roses, and the corolla is white and fragrant, which can be used as tea fragrance. The flowering period is late spring and early summer. After flowering, the fruit is oval, with hexagonal and six-knife persistent calyx, and the mature fruit turns yellow and orange, which can be used as dye or medicine.

The propagation of gardenia can be accomplished by cutting. In spring, select strong branches with the length of 15 ~ 20 cm, which are more than one year old. After cutting, the root takes about 30 ~ 40 days. Fertile loam rich in organic matter is the best soil for farming. Full sunshine and half sunshine are ideal, but full sunshine is more energetic. Prune once after flowering to keep the tree beautiful and facilitate the next flowering; If the plants are aging, they should be pruned again in early spring. Sexual preference is from warm to high temperature, and the suitable reproductive temperature is about 18 ~ 28 degrees Celsius.
