A plant holder having an elongated base body several passages extending transversely to the base body for receiving wire-shaped fasteners for plants, and a clamping device disposed on one end of the base body for affixing the plant holder on a holder to be fastened in the floor or on a wall. The base body has latching protrusions associated with the passages for detachably fastening an end of the wire-shaped fastening means that is bent away and extends substantially parallel to the base body. The wire-shaped fastener for the plant can thus be easily and very rapidly attached to the base body and detached again, without requiring a tool or other resources. With the clamping device, the base body of the plant holder can be quickly attached to a rod or tube with a large holding force and just as easily detached again, also without the use of tools.
