The flowering period of Lagerstroemia speciosa is from June to September every year. Lagerstroemia speciosa, which originated in Asia, is distributed in tropical and subtropical regions of China. Ziwei flowers are red, purple and white. Lagerstroemia indica is known as "Hundred Days Red" because of its bright colors and long flowering period.

Yang Wanli, a poet in Song Dynasty, once wrote poems in praise:

It's good to be infatuated with weakness, but exposure to pressure and bullying is particularly oblique.

Who said that flowers bloom for a hundred days and crape myrtle grows for half a year?

The Southern Song Dynasty poet Wang also wrote such a poem:

In midsummer, green covers your eyes, and this bonus is all over the world.

Shameless all day, not Ziweilang.

Here, Ziweilang refers to the official position of "Tang Shu Xie Ren", according to which: "In the first year of Kaiyuan, the book was changed to Ziweiling, and the life book was Ziweiling."

After the Tang Dynasty poet Bai Juyi became an official,

There is a poem "Wei Zihua":

Your writing is quiet, and the bell and drum tower are long.

Who is the companion sitting alone at dusk? Wei Zi Flower versus Ziweilang.

In ancient poetry, osmanthus fragrans is often accompanied by the expectation that ancient scholars are eager to show their talents, and the long flowering period of osmanthus fragrans is also a commendable feature in poetry. In Zhabei Park, the flowering period of Osmunda japonica can be longer under the careful cultivation of maintenance personnel.

According to director Jiang Haibin, the maintenance personnel in the park have received the guidance and training from relevant experts and mastered more scientific pruning and maintenance techniques.

Adopting the most suitable pruning method for Osmunda japonica can prolong the flowering period of Osmunda japonica.

Lagerstroemia speciosa has graceful posture, smooth and clean trunk, twisted branches, slender branchlets and smooth bark, which is gray or grayish brown.

The posture of the branches is even more dragon and phoenix dancing.

Jiang Haibin, director of the garden, said that the various forms of Osmunda japonica in the garden were not formed overnight, but were cultivated through manual intervention in daily maintenance.

By retaining the lateral branches in a specific direction in the pruning process, Osmunda japonica has shown different postures in the growth process for many years.

At present, Wei Zi in Zhabei Park is gradually opening up, and several of the most flourishing "Star Wei Zi" are in bud, and will soon appear.

In addition to Osmunda japonica Thunb, hibiscus and oleander in the garden are also in full bloom. Visitors can show their nucleic acid negative certificate within 72 hours, and then they can enjoy the cool and flowers in the park.
