Do you know what kind of tree is it? Does it bloom? Color? Since the tree is focal to the front view of your home, you might want to chose plants for either side and around it that will look nice with it when it is in full bloom (assuming it blooms). As has been said, we need to know where your home is to make any suggestions. Having a reddish/orange brick myself, I personally don't like the look of red blooms near the brick. White blooming shrubs look stunning against brick that color, however. So perhaps some white snowball bushes or white spirea would be nice in the back along the brick. Blue plumbago or hydrangeas along the wall behind the tree would look nice. Tall Phlox in front of those and then perhaps some low verbena in a variety of color choices would look nice in front of everything, down low. A circle of purple or yellow iris bulbs planted around the tree trunk would be stunning as well.
