Step on It

Paths and walkways become intimately tied to the garden when interplanted with rugged groundcovers that can handle light foot traffic.

Stone paths, brick walkways, pavers that welcome a visitor to amble throughout the garden; these are elements that tie together a landscape and provide structure and flow. Such components encourage participation and become a permanent part of the site.

But sometimes hardscape needs to be softened, and nothing does that better than the addition of groundcover plants tucked among the rock-hard elements that pave our way. There are dozens of selections of low-growing groundcovers in the trade, but those that are best suited for garden paths are able to take a bit of abuse. So the best way to categorize them is to determine how much foot traffic they can withstand - light, moderate or heavy. Keeping in mind individual cultural requirements, such as sun exposure and moisture needs - not to mention your clients' preferences - you're bound to find the perfect plant for the garden path.



Green carpet rupturewort (Herniaria glabra) provides a lush cover that seamlessly blends pathways into the garden.

Branded plants

There are several brands of groundcover plants that can withstand the abuse of work boots - or sandals - which makes the job of selecting appropriate pathway plants a snap. Remember to verify just how much foot traffic a variety can handle.
