What did the red rose tree tell the nightingale in "The Nightingale and the Rose" by Oscar Wilde.

In the beautiful story about altruism, true love, and deception, "The Nightingale and the Rose," a nightingale overhears a young scholar from Oxford talk about how desperately he wants to please this one young lady that he presumably loves.

In the beautiful story about altruism, true love, and deception, "The Nightingale and the Rose," a nightingale overhears a young scholar from Oxford talk about how desperately he wants to please this one young lady that he presumably loves. 

The girl said to him that she will offer him a dance if he brings her red roses, however, there are no red roses in the student's garden. 

The nightingale, feeling that she has witnessed an instance of true love, feels that she should secure a red rose for the student so that he can complete his wish. However, upon looking around the garden she, too, realizes that there are no red roses at all. 

There is a red-rose tree, however, but it cannot produce the red rose the bird so badly needs. Upon inquiring, the rose tree responds to the bird that the cold winter froze the tree down to the root, therefore, it would be impossible to produce a red rose. 

My roses are red, [...] But the winter has chilled my veins, and the frost has nipped my buds, and the storm has broken my branches, and I shall have no roses at all this year.

This is the pivotal moment in the story when the bird realizes that, in order to get the red rose, she would have to make it herself. She decides, in the name of "True Love", as she calls it, to get a white rose and use her own blood to stain it red. It is the ultimate sacrifice, and it shows the altruism of the bird in wanting the young man to get his wish granted. However, we will find out later in the story that the sacrifice means nothing, as the student is not truly in love and is, in fact, just a capricious and selfish individual.
