im building a burm in front of my house. i need some help with tree/shrub design.i was thinking maybe some dogwoods, bradford pear,cherry tree. i want the trees to keep there uniform shape,that keep the branches up(no low growing branches) and some color.as for the shrubs i was thinking some barberrys, gold thread cypress,and these purple things i see everywhere(cant think if the name). what do u think? the burm is 100 ft x 8 ft .any other ideas?
