1. Camptotheca acuminata is a climbing plant that can climb against the wall without supporting itself. It comes in three varieties: orange, pink and yellow. Yellow and pink can withstand the low temperature of-10 degrees, and the branches will freeze to death if the temperature is lower. We can choose ordinary orange ones, which can withstand the low temperature of MINUS 20 degrees. We can choose reasonably according to our local environment. As long as we plant them, we can climb all over the walls and bloom for a long time in summer. Morning glory is beautiful hanging on it.

2. Clematis is a typical climbing plant, which has strong low temperature tolerance. Only evergreen varieties can not tolerate low temperature in winter, and should be raised in an environment not lower than MINUS five degrees. Other varieties will do. Plant against the wall, choose several varieties, about one meter, and raise a small seedling to climb the wall every year. By then, it will bloom beautifully in spring and last until summer.

3. French perfume vine is a popular network celebrity plant in recent years. Its flowers are yellow, like morning glory, and they smell good. It also has a certain cold tolerance, but don't listen to them saying that it can withstand the low temperature of MINUS 20 degrees. In fact, it won't freeze to death at MINUS 10 degrees. When the temperature is below-10, the branches will freeze to death, and the whole plant will freeze to death below-20. We just need to plant against the wall and see enough light. A middle-aged seedling can climb the whole wall in one year, and then it will bloom and smell fragrant all over the garden.
