Ground cover has many different uses in the garden.
It can be used to help reduce the amount of weeds that will appear in the garden by covering over the space between plants where the weeds might grow.
There is a downside to this though, as weeding can become a bit more difficult when you need to remove the weeds that will still invariably grow in amongst the ground cover.
Ground cover can also help to keep the moisture in the soil by stopping it from drying out from direct sunlight.
It can also add color and texture to the garden.
A lot of the ground cover that is available can supply a splash of color right throughout the year where some will have color in their leaves and then additional color when they flower.
Being so close to the ground they can stay in better condition in windy conditions where they aren't quite so exposed as other flowering plants.
Most ground cover is quite durable and it is an excellent way to add color to gardens that are in conditions where other flowering plants might not survive.
Some ground cover plants grow very well and thrive in shaded areas where other plants might struggle to survive and they generally require very little maintenance.
They are also excellent for creating borders around gardens where there are larger plants or trees growing or where other plants won't be able to get sufficient nutrition to grow to their full potential.
They are particular good for covering areas that are not easily accessible and would normally be too hard to maintain if you were to attempt to grow other plants there.
They also make a nice display when grown in and around rocks and sculptures in the garden and can make a nice mat when grown at the foot of a garden seat, provided of course that you choose one that is durable enough to withstand light foot traffic.
