Are you looking for a cottage feel? If so, you may not want to do the shrubs that were suggested. I would go to a local nursery and talk to them about what you like. They can make excellent recs for plants and growing tips.

Cute house and porch! Here are some questions you need to answer: Do you know what planting zone you are in? It looks like at least half of the gardens are shady. How much sun do they get, and is it morning or afternoon sun? Lastly, how much maintanence are you willing to do (a lot of flowers require regular upkeep)?

Thank you for the compliments and advice so far. To answer some of your questions:
I'm in Zone 5b
the beds have mulch
The porch faces north. The right half including the right half of the front gets afternoon sun. The left side gets much less sun.
I'd prefer less maintenance.
I would like a cottage type feel. The house is surrounded by woods so I think this is appropriate.

Never ever use red mulch - you need dark brown or black for a bed to appear grounded. I however would first work on your house. You don't paint the ceilings if you have a leaking roof. Unfortunately your house has really been compromised by past remodeling.

I appreciate your opinion Old House Guy and I'm aware of issues with my house. We've already done a lot of remodeling to correct past neglect and poor work and we plan to do more, but I asked a specific question. I'd appreciate it if you'd stick to the topic at hand.

I love your house!

My house was covered with shrubs when we bought it and you could hardly see it. I decided I wanted the front to be open, so I planted low plants like catmint and vinca and add height with seasonal Mandeville. Enjoy the journey, it's so much fun.

I thought about planting catnip (which is related to catmint) to help keep Mosquitos and whatnot away. Is it tough to keep it from spreading like crazy? I've heard mints tend to take over.
