Gardenality.com's Answer · Hi again Pam,
That's great. I'm from Ga. as well and have been in the retail nursery and landscape industry for 34 years. We are almost directly west of you. Our nursery specializes in perennials. We have everything, but we are known for our great selection of perennials. That being said we don't have near the selection in the fall as we do during the spring and summer.
Your question is a great one. Many perennial growers grow their plants in a controlled environment that keeps the plant from ever going dormant. Even in the winter their plants, that should be dormant, will be flushed with tender growth. Some growers keep the new growth forced throughout the year. This is very important when considering whether or not to plant a perennial in Zone 8 during the fall. If a perennial has been grown outdoors or at least in a greenhouse that is NOT artificially heated through the cold season you can plant it during the fall. If the new growth has been forced, the plant shipped to a nursery, and then you buy it, it would be highly susceptible to cold shock or freeze damage. So ask before you buy to make sure the plant has been allowed to go dormant or if it's got forced new growth. If they say it came fresh out of a greenhouse...don't buy it. Or if their perennials are in a heated greenhouse don't buy them. Only buy plants that have adjusted to the colder weather.
Many perennials are safe to plant in the fall or even the winter months. Black and Blue Salvia is among the list of good perennials to plant in the fall. Just make sure that they have been allowed to go dormant normally.
Here's a few more of my favorites:
