Pepco and the Arbor Day Foundation are giving away free trees to reduce utility usage, increase air quality and improve stormwater drainage. Check out this link - there is a great interface to map where around your home is the most efficient planting zone based on heat produced by the sun. You can choose between Crapemyrtles and Redbuds which both look great since the spring bloom!
