A hanging basket (1) for plants comprising or including a hollow-walled housing (2) having a water reservoir (4) at its base and apertures (5) in the walls of the housing above the reservoir, a water inlet aperture at the top (3) of the housing and a water outlet aperture in the form of a weir (6) in the reservoir, through the upper end (6a) of which excess water can flow from the reservoir out of the bottom of the basket, and a cowl (7) above and spaced from the upper end of the weir, the cowl preventing or inhibiting water or growing medium from directly entering the weir from above, the arrangement being such that water entering the water inlet aperture can only leave the basket through evaporation via the plants or the growing medium, or by drainage via the weir.
