Spend on the wind. If the wind is strong enough, it will fall with the wind. If flowers are under the wind, they won't fall with the wind.
In addition, the state of flowers will also affect whether they will fall with the wind. If the flowers are already in bloom and the petals are unfolded, it is easier to be blown away by the wind. If the flowers are not in full bloom or the petals are not unfolded, they are unlikely to be blown down by the wind.
Generally speaking, where the flowers fall depends on many factors, including the direction and intensity of the wind, the position and state of the flowers, etc.
