     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to  FIGS. 1 through 7  thereof, a new landscaping device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral  10  will be described. 
     As best illustrated in  FIGS. 1 through 7 , the landscape edging device  10  generally comprises a planar base  12  having a concave end  14  and a convex end  16 . The concave end  14  of the base  12  is semi-circular and the convex end  16  of the base is also semi-circular. A planar divider  18  is coupled to and extends upwardly from a top surface  20  of the base  12 . A longitudinal axis of the base  12  is coplanar with a longitudinal axis of the divider  18 . A length of the base  12  is equal to a length of the divider  18 . Similar to the structure of the base  12 , the divider  18  has a concave end  22  and a convex end  24 . The concave end  22  of the divider  18  is positioned offset from the concave end  16  of the base  12 . The concave end  22  of the divider  18  is also offset from the concave end  14  of the base  12 . To provide proper alignment during use, the offset between the divider  18  and the base  12  is by a distance equal to a width of the base  12 . 
     A radius of the concave end  16  of the base  12  is equal to a radius of the convex end  14  of the base  12 . Thus, the convex end  14  of the base  12  is matingly insertable into the concave end  16  of the base  12  of an adjacently positioned edging device  10 . For proper alignment, the radius of the concave end  16  of the base  12  and the radius of the convex end  14  of the base  12  are each equal to half a width of the base  12 . 
     A radius of the concave end  22  of the divider  18  is equal to a radius of the convex end  24  of the divider  18 . Thus, the convex end  24  of the divider  18  is matingly insertable into the concave end  22  of the divider  18  of an adjacently positioned edging device  10 . The radius of the concave end  22  of the divider  18  and the radius of the convex end  24  of the divider  18  are each equal to half a width of the divider  18 . 
     In use, the device  10  permits a method  30  of landscaping curved edges. A first step  32  of the method  30  is to provide a plurality of the devices  10  as described above. Another step  34  is to position each landscape edging device  10  adjacent to another landscape edging device  10  forming a line  36  of the edging devices  10 . A step  38  of angling each landscape edging device  10  relative to an adjacently positioned device  10  forms the curvature of the line  36  of edging devices  10  that conforms to a desired shape. Another step  40  is embedding the base  12  of each device  10  into a ground surface  42  such that the top surface  20  of the base  12  is substantially coplanar with the ground surface  42 . Thus, the divider  18  of each device  10  extends upwardly from the ground surface  42 . The aligned dividers  18  provide a well-defined border while the base  12  extends outwardly from opposite sides  46  of a base  44  of the divider  18  by a distance sufficient to prevent weeds from spreading under the base  12 . The width of the base  12  is also sufficient to permit a lawnmower  50  to be passed over the base  12  such that the blade  52  of the lawnmower will cut grass extending up adjacent to an outermost edge  48  of the base  12  when a deck  54  or tire  56  of the lawnmower  50  is adjacent to the divider  18 . Material  58  such as mulch or stone may be positioned within an area  60  defined and surrounded by the devices  10 . 
     The base  12  may have a width between about 18 and 20 centimeters and a thickness between about 3 and 4 centimeters. The length of the base  12  may vary greatly to facilitate forming straight sections but is typically between about 20 and 40 centimeters. The divider  18  may have a height between about 20 and 25 centimeters, a thickness between about 3 and 4 centimeters, and a length equivalent to the length of the base  12 . 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure. 
     Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure.
