Hollow rockery stones, replicas of natural rocks, made of plastic or any suitable material which is weather proof and damp proof with draining holes in the base and open at the top. Placed where they are wanted with the top being open they can be filled with any suitable material topped with soil, compost or suitable material to grow rockery plants. One or two holes in the sides provide additional places for plants. Anyone not able to lift real rockery stones could easily use these to make a rockery or have them free standing. Edging a path or on a patio for example.
