Botanical Name: Fucus vesiculosus
Country of Origin: Canada
English Name: Bladderwrack
Also Known As: Bladder Wrack, Fucus vesiculosus, Rockweed, Sea Oak, Black Tang
Part Used: Dried thallus of Fucus vesiculosus, cut and sifted
Description: Bladderwrack C/S is produced from the dried thallus of Fucus vesiculosus, a brown seaweed found along the cold, rocky coastlines of the North Atlantic and North Pacific regions. This marine plant grows attached to tidal rocks and can reach lengths of 1–2 meters, with flat, branching fronds and characteristic air-filled bladders that help it float in shallow coastal waters. After harvesting, the seaweed is rinsed to remove natural ocean debris, dried to preserve its structure, and cut into uniform pieces suitable for culinary and craft use.
Fucus vesiculosus develops broad, olive-brown fronds that vary in shape depending on tidal exposure. When dried and processed, the fronds maintain much of their natural colour variation and layered texture. The cut-and-sifted form produces manageable fragments with a firm, slightly leathery character typical of dried marine botanicals. The processing steps focus on preserving the natural appearance and form of the plant while producing an ingredient that is easy to incorporate into blends and displays.
Collected seaweed is washed, naturally or warm-air dried, and mechanically cut and sifted to achieve a consistent particle size. This retains the plant’s original structure, making it suitable for both culinary use and creative marine-themed crafts.
Uses: Bladderwrack C/S is used in culinary seasoning blends, broth-style preparations, and salt-friendly flavouring mixtures where dried sea vegetables are desired. It is also used in craft projects, educational marine displays, natural art compositions, and formulations requiring dried seaweed for visual texture. Its natural coastal appearance and structured fronds make it suitable for decorative arrangements and creative botanical applications.
Storage: Store in a cool, dry, dark place in an airtight container. Refrigeration not required.
