Abstract: A landscaping block having a block body with at least a first side surface, a second side surface, a third side surface and a fourth side surface, and opposed and substantially parallel top and bottom surfaces. The patio block having at least one spacer projection extending outwardly from each of the at least first, second, third and fourth side surfaces. The patio block having at least one spacer locator positioned along each one of the first, second, third and fourth side surfaces. The at least one spacer locator positioned along each side surface has a retaining surface shaped to receive a spacer projection, at least a portion of the retaining surface extending outwardly from the side surface.

Abstract: An artificial flagstone for use in combination with other similar flagstones for covering a surface with a natural random look, the flagstone having a generally hexagonal body comprising a first, second, third, fourth, fifth and sixth consecutive vertices; a first pair of first and second sides extending radially from the first vertex; a second pair of third and fourth sides extending radially from the third vertex; a third pair of fifth and sixth sides extending radially from the fifth vertex; wherein the sides of at least one of the first, second and third pair of sides have at least one split deviation along their length and are respectively rotational images of each other, and the artificial flagstone has no rotational symmetry when rotated about a central axis.
