My family has had many landscaping project peformed by Moffet's and we could not be happier. Their work is both professional and beautiful. From the plant choices, to the coordination to the actual execution of the job, I highly recommend Moffets. Quality is always busy, so get your name in early for jobs in the summer.
If you are just shopping for plants, I've found their offerings perform much better than any national chain (sometimes cheaper, but if it doesn't grow well, what the point right?).
