Edges are narrow planting strips that demarcate zones, such as lawn-to-flower bed transitions, pathways, or garden sections. They establish structure, direct flow, and improve aesthetics with defined lines in landscape design.
Edging plants should be compact, dense, and low-maintenance. Examples include:
| Group I | Group II |
| (P) Edge City | (1) Rapid expansion of geographical areas of towns or cities |
| (Q) Synekism | (2) Violence against the city |
| (R) Urbicide | (3) A secondary CBD on the edge of the city |
| (S) Urban Sprawl | (4) Rebuilding core city area |
| (5) Union of several small urban settlements under one rule |
