What is Polycarpa
Polycarpa or iigiri (Scientific name Idesia polycarpa) is a deciduous tree in the family Salixceae, native to Japan, Korea, China and Taiwan. Japanese name "Iigiri" comes from the fact that it was used to wrap rice. Yellow-green flowers (actually calyxes) bloom from spring to early summer. There are no petals, but rather five yellow-green sepals that look like flower petals. In the fall, the branches are filled with red fruits in large clusters. The red fruits, after the leaves have fallen off, are used in floral arrangements.
