DE, I have been meaning to tell you about pachysandra.
If you're not familiar with it, I can't recommend it highly enough. It stays green all winter and it's almost impossible to kill.
You plant them in places such as hills or other areas that are difficult to mow or keep green all year round.
Ideally, if you dig or pull up somebody else's pachysandra, you don't have to pay for them, in addition to the fact that they grow like wildfire.
You might like them/find a need for them around your property.

It is a ground cover that needs almost NO maintenance.
