This might be due to the climate zone you are in. This is a somewhat cold-hardy bush, so if you are somewhere where it is relatively mild this can happen. It may be that the bush has grown mature enough to be hardy in your area. Usually they will lose their leaves for the winter though. This article will give you information on the care of the bush: https://www.gardeningknowhow.com/ornamental/shrubs/burning-bush/burning-bush-care.htm
