A water drainage edging segment includes a horizontally-extending bottom portion, a vertically extending top portion, and an angled intermediate section spanning between the bottom and top portions. The bottom portion defines a plurality of longitudinally spaced bottom channels that are oriented at one or both of a perpendicular angle and an oblique angle to the longitudinal axis of the edging segment. Each of the plurality of bottom channels are raised above a lowermost plane of the bottom portion to define an open passageway from a backside of the edging segment and laterally through the edging segment. The top portion defines a longitudinally extending upper rib portion that projects rearwardly from a front plane of the top portion to define a forward offset of the front plane and an upward facing contact surface.
