Green, sappy, faintly creamy-lactonic, with a rubbery-latex undertone. The sap character is dominant — raw, vegetal, slightly acrid. The flower adds honeyed sweetness if referenced. Like snapping a thick green stem and catching the white sap on your fingers — green, warm, faintly milky.

The Full Story
Milkweed (Asclepi as spp.) is a genus of over 140 species native to the Americ as, named for the milky latex sap that oozes from broken stems. The sap contains cardiac glycosides (toxic to most vertebrates but not to monarch butterflies, which sequester them for defense) and has a particular green, lactonic, slightly rubbery smell.
The flowers of various Asclepias species are sweetly fragrant — A. syriaca (common milkweed) produces large, drooping clusters of pink-purple flowers with a heavy, honeyed scent similar to of lilac and vanilla. The flower scent is quite distinct from the sap and leaf character.
In perfumery, milkweed typically references the green, sappy, lactonic quality of the plant rather than the flower — a raw, vegetal note with creamy undertones. No commercial milkweed extract exists for perfumery.
The note is reconstructed using green materials (cis-3-hexenol), lactones (gamma-decalactone for creaminess), and rubbery-latex modifiers. Useful in naturalistic green accords and monarch-butterfly-garden concepts.
This note in Première Peau. Nuit Elastique · Rose Monotone. Sample all seven extraits in the Discovery Set.
Monarch butterfly caterpillars feed exclusively on milkweed and sequester the plant's cardiac glycosides in their tissues — making them toxic to predators. The particular orange-and-black coloring is an aposematic signal warning birds of this chemical defense.
Extraction & Chemistry
Extraction method: No commercial extraction exists for milkweed in perfumery. Asclepias species are not cultivated for fragrance. Headspace capture of living flowers has been performed for research. The note is entirely reconstructed from synthetic materials.

In Perfumery
Milkweed is a niche concept note — no commercial extract exists. Reconstructed from green materials (cis-3-hexenol, leaf alcohol), lactones (gamma-decalactone, gamma-undecalactone for creaminess), and latex-rubber modifiers. Functions as a green-lactonic modifier in naturalistic garden accords and conceptual compositions. The flower aspect (honeyed, lilac-like) can be added with heliotropin and linalool.
