These have been created out of various accent rocks we have had over the years. The purpose of these are to help you in creating a complete naturalistic garden so you do not see black plastic pots tying your water features and plants together. As often seen in nature rocks do have plants growing out of them and can really look cool when the right plants are used and they are the perfect product for flat surfaces such as decking paving or tiled courtyards where planting is not possible. Available with or without a base. Without a base you can simply cover the existing plant in its pot, just put it over and your done!
