In Beijing today it the same as usual. Its pretty dry, and very hot. The heat is very good for some plants but the dryness isn't so good. Not many plants can survive in such dryness. The plants that there are, aren't in that much need to have water twenty-four seven humidity/water supply. So the climate of Beijing can help in many ways to have different type of flowers an it can also cause harm of not permit a humongous verity of plants in close subtropical areas.
