What a lovely way to symbolize your growing, blooming love! How does plantable paper work? Plantable paper is a biodegradable eco-paper that is made with post-consumer materials (no trees harmed for this paper!) and embedded with seeds. When the paper is planted in a pot of soil, the seeds grow and the paper composts away. All that is left behind is flowers and no waste. It's easy to plant and grow. The wildflower seed mix used in this confetti is as follows: Bird's Eye, Clarkia, Black Eyed Susan, Catchfly, Snapdragon, English Daisy, and Sweet Alyssum. This seed paper has a one year shelf life. Sold in a pack of 100.
