Subject to the approval of the City Council, the Park Committee shall have the power to designate the kind or variety of trees, hedges, plants, shrubs and flowers to be planted in any parkway, park, bridle path or other public land or place; provided, however, that the owners of property fronting on any such parkway, park, bridle path or other public land or place may petition the City Council that such trees, hedges, plants, shrubs or flowers be of a certain kind or variety, but such petition shall be merely advisory to the City Council, and the Council shall not be obligated or bound to follow the recommendations of such petition.
