Living willow structures or fences use live cut rods or withies, which are inserted in the ground, & take root. Willow sculpture may use green wood but the rods are not planted, therefore the sculpture should be preserved if you desire your outdoor art to last more than five years.
Wiktor Szostalo and Agnieszka Gradzik create environmental art pieces that are literally tree huggers. Their willow statues and sculptures are twigs, vines, sticks and branches woven together and entwined to create wicker people that wrap their arms around tree trunks. Great for the garden.
