A plant column comprises a substantially columnar casing defining a substrate containment space for containing a plant growing substrate. The casing has a substantially vertical first wall portion and means defining a plurality of plant pockets each with a corresponding opening through the first wall portion. Each plant-pocket defining means includes a respective curved lower wall portion extending obliquely upwardly outwardly from the first wall portion and forming a support for a root-ball of a plant and a respective curved upper wall portion extending obliquely downwardly inwardly from the first wall portion and forming a support for the plant growing substrate above a corresponding opening of the plant pocket through the first wall portion. In one preferred form, the plant pockets are substantially vertically aligned, and the upper wall portion of each pocket substantially merges into the lower wall portion of the next pocket thereabove. In a second preferred form, the plant pockets are vertically spaced, with each lower wall portion and the corresponding upper wall portion constituting parts of a pipe which is received in a corresponding hole in the first wall portion, the pipe including abutment portions which lockingly engage edges of the hole.
