I'm planning on putting three azaleas in front of my house. Went looking yesterday, and found them in various sizes. I usually buy small and let things grow, but I don't know anything about azaleas. Are they slow growers, and should I get the bigger plants? We want to sell our house next year -- not sure how the smaller plants will grow! (Yet I am feeling frugal.... and want the smaller ones...)

Thanks!
