Abstract: Disclosed is a hanging basket liner for lining wire and other types of hanging baskets designed to hold live, growing plants and flowers or artificial plants or flowers. The liner is of a construction which incorporates a covering of sphagnum moss on its outer surface, so that it has a natural appearance. The flexible material from which the inner liner is made is adaptable, by cutting and trimming, to fit various sizes and shapes of hanging baskets. The liner, which has a diameter in the range from 17 inches to 48 inches and a thickness in the range from 1/4 to 1/2 inch, has a inner lining with sponge like properties which retains moisture, reduces the drying out of the growing medium and is durable, long lasting and reuseable. The liner has a number of vanes emanating from its center so that side slits, through which trailing plants can grow, are created as the liner conforms to the shape of the hanging basket.
