A flower pot assembly for keeping at least one plant temporarily alive without having to water it, includes a pot permeable to water in which the plant is potted with the required amount of soil, and a container impermeable to water in which the pot is received, so that a space is formed between the pot and the container. A gel formed of a water-absorbing polymer and water at least partially fills the space between the pot and the container. The container and gel are used as a packaging for the potted plant in order to keep this plant alive without having to water it during transport and when put on display for sale.
