You have to include Molbak's on any list of garden centers in Seatle, simply because it's the biggest. Seriously, you could spend half a day here looking at the many varieties of plants. Not at the top of my list only because it is too expensive, as compared to the others; dream a little dream, however, and go there. After 3 visits, this experience is consistent; the employees will help you if you are willing to find or wait around for them.
Pros: best selection in town - garden furniture, too
Cons: $$$$; employees hard to find
