Daffodil flower is the flower of spring because they bloom during this season. With their floral beauty they welcome the spring season.
The sweetness of this flower is amazing and had been used for manufacturing perfume in the perfume industry. It was used for the same purpose in the past by the Arabians, Persians and the Romans. The Chinese people have a tradition of keeping this sweet flower in their home during New year's Eve.
The yellow center is called bulb and it can be of any shape like round, oval, pointed. I think someone must have planted the flower here in the woods or it might have reproduced asexually to this place. That might be possible lol but they are vulnerable in open places like this when there are nobody to care against pest and other insects which might affect Daffodil and its tender beauty.
