White Rose with Larkspur No.2

I believe this image holds no specific audience or gaze, but rather is an observation of the painter. The observer is allowed to notice the natural shapes the rose takes on in this painting. Owing to the fact that this rose is an older rose, blossoming, it offers many angles and forms. If it were a newer rose, just in bloom, the shapes would undoubtedly be different.

What purpose is behind the painter choosing to paint this rose at this stage?

I feel that the viewer is positioned also as an observer, just as the painter is. The difference is, we are observing the observation of the painter in its finished state. We too can see the shapes inside and outside of the rose and larkspur and the specific state both are in. We can see the very interesting shapes formed in the center of the rose, which seems abstract. We also notice the condition of the rose. Seeing that it is indeed in full bloom, the pedals are beginning to tear and curl at their edges.

O'keeffe was careful to capture all of the details of this flower to effectively allow the viewer inside of her observation. She even captures the shadow it leaves on the surface it is sitting on, which seems to have a similar hue to the larkspur in the picture.

Further more, after looking up what type of plant Larkspur is, I was informed that this plant bears spikes.

With that knowledge, how does that affect the meaning of the painting and/or observation?
