PROBLEM TO BE SOLVED: To improve absorption ability for water, especially prolong the life of flowers when the flowers are inserted to the depths of a frog by boring through openings of a specified diameter from the tip to the bottom of all needles of the frog so that water is well distributed to the flowers. SOLUTION: A through opening of approximately 14 mm in diameter is bored from the tip to the bottom of a frog needle 1, and the needle 1 is supported by a stopper 2 to form a frog. The frog is colored in white representing sand, green representing glass, or brown representing earth. When flowers are inserted between the depths of the frog needles 1, absorption ability of the flowers for water is improved, the display time of the flowers is prolonged, and especially, fresh flowers can prolong its life.
