As living beings, seaweeds exist at the periphery of people’s awareness, and not much is known about what they mean to people, and the relationships we can have with them. They are useful, versatile commodities, and multitask as foodstuffs for people and other beings, as sources of biofuel and medicinal compounds, and the list goes on... but, what else? This work seeks to shed light on the kinds of relations that people can have with seaweeds when relationships of use are purposefully bracketed out, in order to understand their social and symbolic worlds. To this end, during the months of November through January, the author discussed the perceptions of seaweeds with the neighbours of the area of Loch Hourn, a sea-loch (fjord) in the western seaboard of the Scottish Highlands, and some other nearby townships. The present study interlaces participant observation nuanced by the winter and the weather, and interviews, to explore how, through relations of biosociality, companionship, awareness and interanimation of the environment, alternative configurations of knowing, Gaelic tradition, symbolism, and hope, seaweeds embody different aspects of the meaning of‘sanctuary’.
