There is described a room fragrancer in which a porous dispersion element (41, figure 5) is linked to a closed reservoir 2 of fragrance liquid by a conduit 10, the arrangement being such that in a first position the fragrance liquid may flow through the conduit and be exposed to a part of the dispersion element, and in a second position the fragrance liquid drains from the conduit into the reservoir. In a preferred embodiment, the dispersion element 41 forms part of an artificial flower head, the conduit is formed in the shape of a flower stem and the reservoir is a vase 2, closed by a closure 5 through which the conduit extends. An opening 21 is formed through the wall of the conduit 10 within the vase 2 and adjacent the closure 5, so that when the vase is briefly inverted the fragrance liquid can enter the conduit through the opening 21 and flow to the flower heads. Part of the fragrance liquid is absorbed by the dispersion elements 41. When the vase is returned to the initial position, excess fragrance liquid drains back from the flower heads into the vase.
