The note unfolds with a profound, cool greenness, immediately invoking the verdant depths of an ancient forest floor after a heavy rain. It possesses a distinct damp, earthy character, reminiscent of rich, dark soil and wet stone, often with a subtle mineralic chill. There's a leathery, almost suede-like texture to its development, imparting a sophisticated dryness that prevents it from becoming overly wet or dewy. Its intensity is deep and grounding, yet rarely overwhelming, projecting with a quiet authority rather than an aggressive sillage. As a quintessential base note, its longevity is exceptional, often anchoring compositions for many hours, evolving subtly into a smoother, slightly powdery earthiness. It has a velvety, moss-covered quality, a deep resonance that provides a crucial foundational element, offering a counterpoint to more fleeting top and heart notes. It is robust, complex, and enduring, contributing significant tenacity.
