The present invention relates to a container for plants. It is essentially characterised by virtue of: a rigid structure (1) formed by at least two uprights (2), one on each side of the container, an upper ring (3), preferably with a quadrilateral shape, supplemented by longitudinal reinforcing lateral slats (4) and transverse reinforcing lateral slats (5); a reservoir (6) for plant substrate, soil or water, supported on the rigid structure; a water reservoir (7), and a system for conveying water to the substrate.
