A Question For The Gardeners Out There

In the past, I’ve dabbled with gardening.  I particularly enjoyed planting flowers at our old suburban home and watching them bloom and grow and flourish.  I liked getting my hands dirty and seeing the product of my manual labor, and I even accepted weeding and watering our small flower beds as a useful weekend activity.

So, a question for the expert gardeners out there:  if you want to learn about gardening practices in Maine, or any other new location, where should you go?  Is there an authoritative guidebook or website that provides information by region and can get into detail about the basics, like the native plant life, the safe time to plant flowers and which ones are most likely to thrive given the climate and soil conditions, whether planting seeds or seedlings is the best course, and whether particular kinds of grasses or shrubs are more prone to succeed or fail than others?  Can you trust the folks at the local hardware store or gardening shop to only offer plants that have reasonable prospects for success given the local conditions, or is that approach doomed to failure?

I feel like a newbie here, and I’m not sure that doing random internet searches and trusting to the Google Gods is the best way to go about gathering information.
