What is a good website to learn what plants I can plant in my yard, how to care for them, what time of year to plant? I live in the Pacific Northwest so a site that is specific to my area and easy to understand would be great. Thanks.

Hi ChihuahuaMomma! I live in Port Angeles,(a bit north of you! Looking at the information gnahcd posted, that puts me in 'zone 4' - couldn't see Vancouver on that map, if you are in zone 4 too, my info may be helpful... ) I've always had success with:
Peonies
Lupine
Hostas
Rhodies
Daffodils
Tulips
Crocus
Dahlias
Iris
Lilac

I don't live I'm Vancouver anymore. I'm in the Portland area. I don't need to know WHAT to grow. I need to know HOW to grow it. I can't keep anything alive...

Oh - my mistake, thought you had mentioned you wanted to know what might work in your yard... maybe this link will help:
