Abstract: A plant packing container for retaining plant freshness has a flexible waterproof sheet laid on the bottom of a container body. An upper sheet overlays the flexible waterproof sheet and covers almost the entire bottom of the container body. The upper sheet retains moisture between the flexible waterproof sheet and itself. The stems of flowers or plants to be transported are inserted through perforations formed in the upper sheet to maintain the relative positions of the flowers or plants during transport. The flexible waterproof sheet is then folded over and wrapped around the plants held by the upper sheet. The packing container maintains an appropriate internal humidity level and minimizes factors which can cause the flowers or plants to be cut or spoiled during transportation.
