To provide a flower vase for a tombstone, in which an offered Buddhist's flower is supplied sufficiently with water, which is supported tightly so that the offered Buddhist's flower does not fall and in which a plurality of the Buddhist's flowers can be arranged even in the case of a number of visits to a grave, the temperature of water is not increased in summer and a flower-vase stone is not damaged by freezing in winter.

In the flower-vase stones 10 arranged on both sides of an altar 12 on the front of a grave marker 11, the flower-vase stones 10 are formed in constitution in which bottomed holes 10a in diameters sufficiently larger than the bundling sections of the Buddhist's flowers and depths are bored and dug at the top sections of the flower-vase stones 10, vessels 13 coinciding with the inner sizes of the bottomed holes 10a are fitted into the bottomed holes 10a, skirt sections 14b conformed to opening sections are formed to the upper-section openings of the vessels 13 and cover bodies 14 in which at least one of Buddhist's-flower inserting holes 14a is formed are fitted. In the flower-vase stones 10, the cover bodies 14 are molded of either of stone, ceramics, a synthetic resin or a metal, the inside diameters of the vessels 13 have sizes of at least three times of the thickness of the bundling sections of the Buddhist's flowers, and depths are deeper than the lengths of the bundling sections.
