The two names of wintersweet and wintersweet are correct. They are different names for the same plant.

The scientific name of this plant is Daphne odora, which belongs to the Theaceae family (Daphne). It is an evergreen shrub with a strong fragrance and beautiful flowers. It is also called a winter flower because its flowers usually bloom in winter.

In different regions and cultures, people may call this plant differently. In China, it is generally called wintersweet because its flowering period is usually around the twelfth lunar month (the twelfth lunar month) or the first day of the twelfth lunar month. In other places, such as Taiwan, Hong Kong and some Western countries, people prefer to call it wax plum because its flowers have a waxy sheen.

So, whether it is wintersweet or wintersweet, both can be used to refer to this plant. The specific name used can be determined according to the region and personal habits.
