Here is a photograph to inspire poetry. It is a photograph of a small yellow flower.
There are a number of inspirations for poetry that could be drawn from this photograph.
One is the idea of the stages of the flower. In the photograph, there is a blooming flower, flower buds, and spent flowers. The idea of stages can be used in poetry.
Additionally, this flower could be considered a weed. This could lead to the poetic examination of something like social class (the idea being, why is this flower a weed, but other flowers are not?).
Another idea would be to examine contrast. In the photograph, the yellow flower contrasts with the green plant.
Also, this photograph could generally inspire a nature themed poem.
