Abstract: A vessel for planting plants or flowers has features particularly useful in the field of flower/plant-growing thanks to the advantages for the growth and vegetation of the plants as well as the savings in the transport and storage activities of the vessels themselves. The vessel provides, uniformly arranged in its lateral surface, a quantity of cavities and housings apt to promote the correct growth of the roots; it is made in plastic material through a manufacturing method whose output is preferably the planar development both of the lateral surface and of the base surface of the vessel. The planar development is so utilized during the phases of transport and storage of the vessel, which, in this case, is composed on site at the moment of its utilization, through simple assembling operations.
