The Amazon Bowl with attached saucer is made of biodegradable bamboo and other grass fibers, rice, wheat and corn. The colors are derived from vegetable dyes. These pots are manufactured with a pollution free technique. Although they last 4.5 years indoors and 3.5 years outdoors, when dropped into a landfill they will biodegrade in 3-6 months. This stunning style is available in many colors. Great for all types of plants including bulbs.
