Procumbent plants are plants that trail along the ground. The term, procumbent is often used to refer to landscape plants (vines) that cannot grow upright unless aided by humans through training. The classification, "prostrate" is sometimes substituted. Such plants are alternatively called "creepers."
An example is creeping jenny.
Some mat-forming weeds that are notorious for exploiting cracks in sidewalks, gaps between the pavers in your patio, etc. also fall into this category. Examples include:
- Prostrate knotweed
- Spotted spurge
