The climate in northern and southern China is quite different. So many plants can survive in the south, but not in the north. There is a feeling that "oranges are born in Huainan and oranges are born in Huaibei". Therefore, if you want to plant flowers in the north, you must first understand the climate characteristics in the north. Water shortage is common in the north, so it is necessary to plant ground cover plants with strong resistance. These plants include Ophiopogon japonicus, February orchid, Viola yedoensis and Hosta. These seemingly beautiful flowers are not much different from other flowers. In fact, they can grow in the relatively harsh environment in the north, which can be described as "flowers don't cover their faces."
