Abstract
A container (2) such as a plant holder is provided with formations at its lower end to enable it to be stacked on other such holders in a staggered formation so that none of the supporting containers need be closed off. The containers are polygonal, so that they can be interlocked in edge to edge formation A or corner to corner formation B. Drain holes are provided so as to enable the upper containers of an array to drain into the lower ones and then to supporting trays (3).
