Sharp, green, faintly citrusy weed. Horseweed (Erigeron canadensis) smells like crushing a roadside plant -- pungent, herbaceous, with a turpentine-like top and a lemon-grassy edge.
Sharp, pungent, herbaceous-green with a turpentine-like freshness and a lemon-grassy edge. More aggressive than basil, less clean than rosemary, with a distinctly weedy, roadside quality. The limonene gives it a citrus note; the pinene gives it a piney sharpness. Wild and uncomposed.
Horseweed (Erigeron canadensis, syn. Conyza canadensis) is a common weed native to North America, now invasive worldwide. The plant produces a small quantity of essential oil with a sharp, herbaceous-green, faintly citrusy character. The volatile profile includes limonene, alpha-pinene, and trans-beta-ocimene.
In perfumery, horseweed is a rare note providing a sharp, wild-herbal green character. It is less clean than conventional aromatic herbs (lavender, rosemary), more pungent, and more 'weedy' -- the smell of abandoned fields and roadsides rather than cultivated gardens.
Functionally, horseweed works as a sharp green top-note modifier. It provides a wild, uncultivated botanical reference. Works in wild-nature, green-herbal, and hyper-naturalistic compositions.

Erigeron canadensis was the first weed to evolve resistance to glyphosate (Roundup), confirmed in 2000 in Delaware. It is now glyphosate-resistant across millions of hectares of North American farmland -- making this humble weed a successful evolutionary adapters of the agrochemical era.
Extraction & Chemistry
Extraction method: Steam distillation of the aerial parts of Erigeron canadensis yields a small quantity of essential oil. The oil is not widely traded in mainstream perfumery supply chains.
