The Vegetational fatherhood represents the ultimate communal with nature, where nature and man are able to become one and reproduce. The romantic movement was very influenced by the beauty and mystery of nature, so it seems natural that a writer would go as far as to want the two entities to breed. It seems that the combination of the roses and the woman has created an even better creature. Unfortunately her demise can show the opposition to the romantic movement. Her husband, a doctor and therefore a man of science throws his bride out the window because she looks like a rose bush. Perhaps the author wanted us to begin thinking about nature as human, that the life of a rosebush has the same value as a human life. When the girl looks like a rose bush the doctor throws her out the window without care, because to him she looks like a worthless plant. In fact it is his lovely bride, and by getting ride of the plant, he kills his wife. 

The mother's dream in which the rose bush actually transforms into a man gives the reader the idea that nature and plants have the ability to take on human form. By transforming into man, nature shows us the readers that we two are not that different, that we have the same needs and desires, as well as emotions. The child is devoted to her father, and therefore turns into a rosebush every night. She is the perfect child because she is half way between nature and humanity. She is able to experience both worlds and live in a true Romantic state, able to reach the sublime.
