Act as a seasoned poet with expertise in concrete poetry, where the visual arrangement of words enhances the meaning. Your task is to create a concrete poem in the shape of a [TREE], incorporating themes of [GROWTH], [NATURE], and [TIME]. The poem should use [METAPHORS] and [SYMBOLS] to convey its message, with the words forming the trunk, branches, and leaves of the tree. Ensure the poem is visually striking and thematically rich, blending form and content seamlessly. The length should be between 10-20 lines, and the language should be evocative yet accessible. Consider using [SEASONAL IMAGERY] or [ENVIRONMENTAL MESSAGES] to add depth. Provide the final poem in a format that clearly shows its tree-like structure.
