In the autumn breeze of September, an irresistible aroma quietly pervades. On the morning of September 8, the reporter found that the first wave of early silver laurel in the Shanghai Botanical Garden has opened, and the flower buds of varieties such as dangui on the side have also become fuller, and will follow the "pace" of early silver laurel to bloom one after another, bringing more brilliant autumn colors to tourists.
Entering from Gate 3 of the Shanghai Botanical Garden, visitors only need to turn right and walk straight to see several blooming early silver laurels and silver laurels on the side of the road. Clusters of young yellow flowers like rice grains dot the branches, which stand out especially among the green leaves.
The breeze blows, sending the unique fragrance of osmanthus flowers, sweet but not greasy, making people can't help but breathe deeply and indulge in it. Residents and tourists passing by are attracted by the fragrance of the flowers, they stop to admire the osmanthus trees, and some even take out their mobile phones to take pictures of the autumn colors of this season.
"It will soon be the eighth month of the lunar calendar, the season when osmanthus flowers bloom, and I came here to see it today. Sure enough, this osmanthus blooms, especially beautiful! Resident Wang Arbor pointed to the osmanthus tree and told reporters that the laurel garden of the Shanghai Botanical Garden is very famous, and there are four varieties of silver laurel, golden laurel, dangui and four seasons laurel, "In a few days, the aroma will be more powerful!" ”
The flowering of osmanthus is closely related to temperature changes. Flowering needs to meet the condition that the minimum temperature reaches below 20 ° C, so that the osmanthus can feel "autumn cool" and then gradually heat up. In this process of cooling down and then heating up, the flower buds gradually turn into buds and eventually bloom beautiful flowers.
According to experts at the Shanghai Botanical Garden, as it cools down in late September, osmanthus will bloom in large areas at that time. Residents can visit the Gui Garden near Gate 3 of the Shanghai Botanical Garden to enjoy the unique aroma of osmanthus flowers.
