What do they cost?
As little as $1 to $4 per plant in bare root bundles or by the flat from a nursery or a garden center. Expect to pay $5 to $9 for plants in 4-inch pots and $10 or more for plants in gallon-size containers. Or finagle free starts from a neighbor.
DIY or hire a pro?
Even folks who are new to gardening can handle most groundcover projects, but if replacing an entire lawn or blanketing an expansive hillside, you might want help from a landscaper.
How much care?
Water and weed until the plants fill in. After that, many groundcovers can be virtually maintenance-free.
How tall are they?
The majority are 2 to 18 inches, but they can easily top 2 or even 3 feet. There are also tiny ground-huggers that max out at just 1 inch tall.
