What is the title of Georgia O'Keeffe's painting of a New Mexico tree against a blue sky?

Georgia O'Keeffe's painting of a New Mexico tree against a blue sky is The Lawrence Tree.

O'Keeffe painted The Lawrence Tree in 1929 while visiting New Mexico. It shows the underside of a large ponderosa pine, with its branches spreading across a deep blue sky. The unusual viewpoint transforms an ordinary tree into a bold, nearly abstract pattern of dark limbs and bright space.

The painting is associated with D. H. Lawrence, the English writer. O'Keeffe painted it near the ranch where Lawrence had stayed, close to Taos. The location helped connect the work to the literary and artistic communities that gathered in northern New Mexico during the period.

The Lawrence Tree is often discussed as an example of O'Keeffe's ability to make a landscape feel both recognizable and unfamiliar. She did not simply record a tree from eye level; she selected a dramatic viewpoint and simplified the composition. That approach also appears in her flower paintings, bone paintings, and architectural subjects. The work is sometimes confused with her flower series because both enlarge a single natural form.
