The origin of the name iris is from the Greek goddess for rainbow. One of the distinctiveness of iris flowers are the flowers and leaves. Enjoy these all year round. Material of flowers are made from PU (Polyurethane) and stems are made from plastic and metal wire. Notes: when silk flowers arrive, unbend the stems and layout the irises for some room to breathe, slightly puff the petals and re-arrange the stems to desired effect. Keep away from sunlight, color will lighten with time. If placing outside, use as flower for grave or for cemetery flower vase as example, exposure to the sun and external elements like rain, snow and hot and coldtemperatures will likely, in long-term affect the color to fade overtime which is a normal process like for most artificial plants or fake plants. Notes: the color of fake iris flowers may vary due to differences in monitor displays
