A vase for flowers and plants is described which, thanks to an integrated air dehumidification system, composed of a refrigeration unit, is able to produce water for plants autonomously, without being connected to any water supply or without water added by an user. Through a moisture sensor placed inside the soil, it is possible to evaluate the moisture level of the soil itself and, through a pump, to deliver the produced water to the plant until the set moisture level is reached. Independently from the plant exposure, in a sunny or shaded area, from the season, both summer and winter, and even without the presence of a person, the vase is able to provide the necessary water supply to the plant. The invention meets the needs of vegetal species in the vase and also, if it is placed inside a house or an office, is able to improve the environmental comfort, reducing air humidity and providing oxygen thanks to the symbiotic relation between the vase and the plant.
