Plant blindness is a concept that has long been ignored by researchers and teachers. It brings integrated overview about “plant blindness” research history and it can serve as a springboard for other researchers. The aim of this study was to identify how research studies represent the concept of "plant blindness." These research studies primarily focus on the education process. The PRISMA model was used for this review study. Data collection took place during spring and summer of 2025, covering studies from 1999 to 2024 related to research on “plant blindness.” Google Scholar was chosen as the information source. Initially, 52 research articles were reviewed; after analysis, 22 studies were selected, while 30 papers were excluded because their main focus was outside the scope of this study. Most of the research studies were published in 2023, the majority of respondents were from the USA, and university students were the most frequent sample group.
