This study explores conceptual metaphors of Have You Ever Seen a Flower? through the theories of cognitive linguistics such as categorization, image schemata, and prominence, attempting to apply cognitive linguistics to English education in this process. The conception that everyday language and poetic language are fundamentally different, and that literary language is a departure from everyday language use ultimately confine the metaphor within the self-sufficient and closed linguistic system or within the poet's imagination, away from our daily lives. For this reason, the metaphor has been regarded as secondary or non-essential in language learning. Yet from a cognitive linguistic point of view, the metaphor is in an inseparable relationship with thinking and cognition. The status of the metaphor in English education needs to be re-evaluated, and it should not be regarded as a secondary learning subject trapped in the stereotype of figurative expression.
