Hmmmm....where to start? I am no Master Gardner, but my mom is (who lives in NC in Hendersonville) One book she highly recommends is the one put out by Southern Living
The Southern Living Gardening Book. It clearly defines the areas and their climate zones. A lot of my gardening tends to be "Survivor Style" which means I research, buy the best plant I can afford, and hope it doesn't get "voted off" the garden LOL.
What kind of plants are you thinking? Flowering Shrubs? Roses? Annuals? Perrenials?
Hostas are great, but make sure you have good shade for them or they will bake. Peppermint will thrive, and as most herbs like heat, you should be ok. Shrubs- you will find crape myrtles do very well here, along with butterfly bushes. I can't tell you how many hummingbirds and butterflies we had last summer (granted this was here in GA) because of these 2 bushes! Lillies do so well here especially the Stella-de-ora variety. Purple Cone flower and all kinds of daisies do great here too.
I have had the best luck with going to a garden center and asking the folks there. Very often you can find the growers reps helping out, and they are a great resource.
Right now I am looking our at my garden, and there is one daffodil that is already blooming, with the rest not far behind. The iris are up about 3 inches, and the tigerlillies are popping out of the ground. Pansies are blooming that I planted last fall, and the butterfly bush already has new growth.
~sigh~ Sadly I can't take most of them with me to NC...but those that I can dig up are coming along for the ride
Hope this helps a little. If you have specific plants in mind I can always consult with mom
