molded as an integral unit from a plastic material or the leaves can be stamped out from a rubberized water proof fabric and the flexible petioles 24 b 1 24 b 2 and 24 b 3 can be extruded from a plastic material and attached by means of an adhesive the flexible matrix like infrastructure 22 is shown in fig1 as a net like unit molded from plastic or composed of extruded rids interconnected by adhesive or thermal welding in any case the infrastructure 22 consists of mutually perpendicular rods such as rods 22 a 1 22 a 2 22 an and rods 22 b 1 22 b 2 22 bn respectively these rods form individual cells with through openings as can be seen in fig1 the cord 26 that is threaded through the openings 24 d 1 24 d 2 24 n in the respective knots 24 c 1 24 c 2 24 n of the petioles 24 b 1 24 b 2 and 24 b 3 is twisted at least once around the points of intersection 28 a 1 28 a 2 28 an of mutually intersecting rods 22 a 1 22 a 2 22 an and rods 22 b 1 22 b 2 22 bn thus securing the decorative elements i e the artificial leaves 24 a 1 24 a 2 and 24 a 3 and their petioles 24 b 1 24 b 2 and 24 b 3 to.
