A few years ago, Nanjing in the laomen east city wall on the inner side of the landscape belt, to create a sea of about 4,000 square meters of rhododendrons, these rhododendrons are not only large flower type, but also the color is very gorgeous, both pink, but also light purple red, dark purple red, as well as red, as well as very rare purple varieties, every spring, all kinds of rhododendrons compete for glory, competing to bloom, just like to tie a color ribbon to the ancient city wall.
Every year, the rhododendron flowering period is short, only in April and May, you can see their fragrance, under normal circumstances, the azaleas should bloom in the spring, but on November 11, the author saw under the wall of the old gate east, the rhododendrons here have also flowered, and the yellowing weeds are in stark contrast, attracting tourists to stop and watch.
There are more than 100 rhododendrons in bloom, some of which are only three or four small flowers that are lonely, and they really can't be noticed without looking closely; some are full of trees, which are very gorgeous, adding some beautiful colors to the walls in early winter. "In fact, the winter flowering of rhododendrons is generally 'potted', cultivated in greenhouses or greenhouses, and the east wall of the gate is wild, almost no special cultivation, rhododendrons generally bloom in early spring, and now they bloom after winter, which is rare," said Mr. Zhou, a tourist.
According to the staff of the Zhongshan Scenic Area Landscape Garden, the normal flowering time of rhododendrons is in the spring. The reason for the anti-seasonal flowering is mainly affected by the microclimate, resulting in the "biological clock" disorder "the recent temperature rise and fall, the range of changes is larger, similar to the weather in April and May, this temperature change makes the flowers and plants mistakenly think that spring is coming, temperature, light and so on inadvertently meet the conditions for flowering, so this abnormal phenomenon occurs."
