Great foundation planting along the front of your house will make good architecture look even better. Allowing wide beds at the base of the walls provides the space needed for a tiered planting effect that helps two story facades more gracefully transition to the ground plain.

Brick, slate, stone, and concrete are known as fixed, or given, elements because you cannot, or probably would not, change them. You could paint brick and vinyl siding, but doing so would only increase maintenance. In general, the foundation color should be the same or darker than the siding color.
