Landscape edging

1. A landscape edging block, comprising:

a shaped structure having a first end and a second end, the first end including a surface that is concave simultaneously along a horizontal plane and a vertical plane, the second end including a surface that is convex simultaneously along a horizontal plane and a vertical plane, and including a top and sides configured to resemble decorative stone,

wherein at least one of the first end vertical plane concavity and the second end vertical plane convexity terminates at substantially the axis of the concavity or convexity, such that a truncated concave or convex shape is formed

wherein the first end of the block is configured to engage a second end of a second block in order to form a landscaping border.

2. The edging block of claim 1 , further including a substantially planar bottom surface.

3. The edging block of claim 1 , wherein the shaped structure comprises cement.

4. The edging block of claim 3 , wherein the shaped structure consists of cement and coloring agent.

5. The edging block of claim 1 , further comprising decorative coloring on the surface of the landscape edging block.

6. The edging block of claim 1 , wherein the first end vertical plane concavity terminates at substantially the axis of the concavity.

7. The edging block of claim 1 , wherein the first and the second ends are functionally configured to minimize a visible transition from one block to another when a plurality of blocks are engaged.

8. The edging block of claim 1 , wherein the top and the sides of the block are configured to resemble a plurality of decorative stones.

9. The edging block of claim 1 , wherein the second side of the block is configured to engage a first end of a second block at a range from a linear alignment to a right angle.

10. A landscape border comprising a plurality of landscape edging blocks as recited in claim 1 , said blocks engaging one another at first and second ends to form an integrated unit spanning a length.

11. The border of claim 10 , wherein the border is placed on a substantially horizontal surface.

12. The border of claim 10 , wherein the border is placed on an inclined surface.

13. The border of claim 10 , wherein at least two of the edging blocks are engaged at an angle.

14. The border of claim 13 , wherein at least two of the edging blocks are engaged at a right angle.

15. The border of claim 10 , wherein the border includes a curved configuration.

16. The border of claim 10 , wherein the blocks are arranged in a manner so as to minimize a visible transition from one block to another.

17. A landscape edging block, comprising:

a shaped structure having a first end and a second end each including a surface that is concave simultaneously along a horizontal plane and a vertical plane, and including a top and sides configured to resemble decorative stone,

wherein at least one of the first end vertical plane concavity and second end vertical plane concavity terminates at substantially the axis of the concavity, such that a truncated concave shape is formed

wherein at least one of the first end or second end is configured to engage an end of another landscaping block having an end that includes a surface that is convex simultaneously along a horizontal plane and a vertical plane.

18. The edging block of claim 1 , wherein the second end vertical plane convexity terminates at substantially the axis of the concavity of the landscape edging block.

19. The edging block of claim 1 , wherein the first end vertical plane concavity terminates at substantially the axis of the concavity and the second end vertical plane convexity terminate at substantially the axis of the convexity of the landscape edging block.

20. The landscape edging block of claim 17 , wherein both the first end vertical plane concavity and the second end vertical plane concavity terminate at substantially the axis of the concavity.
