This creative assembly of permanent components is all made of UV-resistant material. The bright, colorful planting includes Petunia, Gypsophilia, Herb grass, Succulents and Grasses, planted in a natural coco-fiber liner which inserts into a 30" hayrack. The quality hayrack is made of hand-forged steel, dipped in plastic coating to prevent rust, and can be hung on railings, or mounted under a window. (Hardware not included.)
