The invention relates to a water retaining tube for flowers, which comprises a tube body with an opening upward and a cover body. The cover body is a soft body, and the cover body is provided with a through hole through which the cover body can cover the opening of the tube body with a soft operability.With the invention, when water injection is needed, only the cover body needs to be disassembled, and water can be injected into the pipe body simply from the opening of the pipe body.When the cap body is combined with the pipe body, because the cap body is a soft body, the opening edge of the pipe body can be simply covered, and because the cap body is a soft body, there is a continuous combination after the cap body is closed, so it is not easy to exude water.Furthermore, the cover body is provided with a through hole which penetrates up and down, so that the branches of flowers can be inserted.本新型創作係關於一種花卉水分保持管，其包括開口向上之一管體，以及一蓋體，該蓋體為一軟質體，且該蓋體設有一上下貫穿之通孔，以令該蓋體以柔軟操作性蓋合於該管體開口。藉由本新型創作，當要注水時，僅需要將該蓋體拆卸，則可以簡易由該管體之開口注水入該管體內。而要將該蓋體與該管體結合時，由於該蓋體為一軟質體，因此可以簡易套蓋該管體之開口周緣，且由於該蓋體為一軟質體，因此蓋合後有一綿密之結合而不容易滲出水。再則該蓋體設有一上下貫穿之通孔，則可以供花卉之枝部插入。
