Here's why:
* Metaphor: A figure of speech that compares two unlike things without using words like "like" or "as." In this case, "war flowers" are being compared to something fierce and blooming.
* Meaning: The phrase likely represents a contrast between the beauty of nature and the harsh realities of war. The "flowers" could symbolize hope, resilience, or even the aftermath of violence, but their "fierce bloom" emphasizes the intense and destructive nature of war.
The use of metaphor makes the phrase more impactful and evocative, allowing the reader to understand the complex emotions associated with war.
