It all came from nature and we just added efforts to capture the beautiful look and feel of nature longer(average life is 1 year. May differ depending on temperature, humidity and other elements). Approximately 29-32 inch total length. May have different sizes and shades of color in a bunch. Each bunch has about 13-16 stems of pampas. May use for diffusers, flower arrangements, making diy wreaths and more fun and creative home decor ideas.
