New Deck & Stairs

In August of this year, we re-surfaced the stairs down to the pool and the existing deck. We are very happy to have this done and it has made the area surrounding the pool and sunroom look so much more inviting and it certainly has been noticed by our guests. The changes to the decking and improved layout has translated into more use by our guests and even ourself. It seems as though the landscaping and yard improvements are never ending but we find it so rewarding. We like the way it looks and we certainly like the way people have enjoyed the improvements in the yard. We are not quite finished yet but it certainly appears as though we are getting closer to how we would like our yard to be. Next spring we'll be looking at the front of the house - this should be challenging because it is the North side and we'd like to add color if at all possible. Any suggestions for plants that might work?
