Ramon, I have no idea where you posted previously but the suggestion to repost here was way off base :-) This is an exchange forum intended for the trading of plants or seeds. It is not intended to discuss landscaping issues or plant selection - those would be far better addressed on either the Landscape Design forum, Northwestern Gardening (our regional forum) or the Shrubs forum. These are all very active forums and you would have gotten dozens of responses to your request after this length of time instead of just 4 comments. I am very active in all of those but never look here as I don't trade plants - I just saw this in the listing of recent discussions.........

Just for some clarification, you state you want a more "solid piece of landscaping" and then ask about annuals and perennials. Annuals and perennials are generally considered just window dressing in a landscape - the solid stuff is the trees and shrubs that form permanent year round structure. Do you just want to add some temporary seasonal color or are you more interested in a good, year round look?

I am a professional landscape designer and consulting horticulturist by trade and live on the west side of the Sound (after living in Seattle for many years) so I'd be happy to help you fill in your garden if you would like more specific suggestions. You can message me directly if you like (just click on my username and look for the message button) or you can try reposting this on one of the other forums I suggested to get even more input from a broader selection of responders.

Sorry you were sent away to very lightly trafficked and inappropriate forum and not receiving the info you needed in a timely manner.
