PROBLEM TO BE SOLVED: To provide a liane plant strut capable of making vines readily get twisted and changing struts different in length by coating the outer wall of a steel pipe constituting struts with a synthetic resin layer and forming a cylindrical end part on arch member connecting struts. SOLUTION: Three or more struts 1 are stood at proper intervals on the same circumference, the outsides of the struts 1 are engaged with ring-shaped horizontal crosspieces 2 at plural positions, the tops of the struts are connected by arc members 3 bent in an arc shape to give liane struts. The struts 1 are formed by coating the outer wall of the steel pipe with a synthetic resin layer protrusively provided with a great number of projections 21. The arch members 3 are equipped with cylindrical end parts, the cylindrical end parts are externally engaged with the tops of the struts and the top of the struts 1 are connected through the arch members 3.
