To solve the problems in arranging flowers in a cemetery that the volume of water runs short when the flowers are crammed tightly to stabilize them in a flower cylinder, which causes the flowers to die down in a short period, the water in the flower cylinder is apt to rot, and mosquito larvae or the like are apt to hatch.

In a life-extending lid for the flowers to be fitted as a lid for the flower cylinder, a pipe 5 for the flowers is fitted to a flower port 4 formed in the center of the lid 3, by which the flowers are stabilized, sufficient water volume is secured, evaporation of water is prevented, hatch of mosquito larvae or the like is prevented, the flowers become longer-lasting, and bad smell is reduced.
