This design uses some simple and basic methods of accenting the entry walkway of this home while creating flower bed areas on both sides of the walkway. It also creates a buffer from any lawn sprinkler over spray which is especially important if you have colored concrete or paving materials that may be discolored from hard water stains.
The layout of this design has been thought out and as it grows in, will look very nice. The accent character tree in the center of the larger bed will create height and along with its match on the far corner of the home, will create balance.
The planting ideas are simple and repetitious helping to create balance, unity, and continuity. The foundation shrubs which will help break up the the expanse of the front wall are all of the same type. And because of the slope and height of the foundation wall, the shrubs can grow to a managable size without covering up the windows. There will be a little maintenance required with shrubs like these.
The rest of the front yard plants are of just a few vatieties that repeat throughout the yard and landscape. A basic structure like this is so simple to create. You really don't have to do a lot of study of plants. Just look around and see what's working in some nicer landscapes and pick a few. You can always add more later if you want to.
