The term "biophilia" — literally "love of life" — is generally attributed to biologist E. O. Wilson's hypothesis that people have an innate pull toward nature; architecture and interior design later turned that idea into concrete design principles. The point goes beyond potting a few plants: daylight, ventilation and material choice all get treated as ways to bring nature in.
Plants get placed at varying heights, with a floor-to-ceiling planter or a small living wall adding density where there's room. Windows stay as unobstructed as possible so the day's changing light actually reaches the interior, and finishes lean toward less-processed materials like raw wood and stone. Irregular natural patterns — leaves, water ripples — sometimes show up in a rug or wallpaper too.
Without confidence in plant care, the effect backfires fast — overwatered or light-starved plants left to wilt look worse than no plants at all. Starting with a few low-maintenance species and adding more over time is the safer path.
When to use
Use it in a well-lit space where you want to emphasize a felt connection to nature. Without confidence in plant care, start small with low-maintenance species rather than filling the room at once.
