O’Keeffe painting

I recently went to New Mexico and to the Georgia O’Keeffe museum. A lot of people don’t know that she did abstract work. Normally I don’t like abstract but her paintings were interesting and not a marble painting done by a seven year old. I saw this painting and right away felt like I knew what she was feeling. What do you think this painting is about? Please tell me in comments.

Took this at a garden. I noticed that only one flower was in the picture. So I edited it, letting only the flower be in color and the outlining area. There is a reason behind the name, but telling it, to me is like explaining why a joke is funny.
