The Story
Why it exists.
Trimerous was born in 2019 when perfumer Euan McCall set out to celebrate the iris flower’s three‑petal geometry. The name itself, meaning “three,” points to the triptych of facets the scent explores: the fresh, the muted, and the discarded. Drawing on Jorum Studio’s Scottish roots and its love for playful, nature‑driven narratives, the fragrance aims to capture the unspoken joy of an iris in bloom, rendered through a modern, poetic lens.

The Beginning
Trimerous was born in 2019 when perfumer Euan McCall set out to celebrate the iris flower’s three‑petal geometry. The name itself, meaning “three,” points to the triptych of facets the scent explores: the fresh, the muted, and the discarded. Drawing on Jorum Studio’s Scottish roots and its love for playful, nature‑driven narratives, the fragrance aims to capture the unspoken joy of an iris in bloom, rendered through a modern, poetic lens.
What makes Trimerous stand out is its focus on orris butter, a rare, buttery extract that usually hides behind sweeter florals. By pairing it with carrot seed’s earthy nuttiness and angelica’s herbal lift, the composition uncovers layers of the iris that are often overlooked. The inclusion of suede and incense adds a tactile, almost tactile quality, turning the scent into a sensory sketch of an iris seen through three distinct lenses.
The Evolution
The opening bursts with a crisp bergamot snap, pink pepper’s bite, and juniper’s piney lift, quickly giving way to thyme’s herbaceous sting and a whisper of peach that sweetens the air. As the heart settles, carrot seed introduces a warm, nutty earthiness while angelica adds a sweet‑herbal nuance, framing the prized orris butter that lies beneath. Mid‑drydown, the orris dominates, its powdery elegance supported by ambergris’s marine shimmer and the smoky depth of agarwood. Vanilla, musk, suede, incense and styrax linger like a well‑worn book, creating a creamy‑leather finish that persists for the full 6‑8 hour span, leaving a subtle, refined trail on skin and clothing.
Cultural Impact
Since its 2019 release, Trimerous has become a staple in the niche iris niche, often cited as Jorum Studio’s bestseller. Its playful yet sophisticated take on orris earned praise in fragrance forums for redefining powdery florals without veering into saccharine territory, positioning it as a go‑to scent for those seeking a refined, unisex statement.
