Jason,
Well, even if the old plants do return, there's nothing wrong with having
more 'Black & Blue'! (and the hummingbirds agree, I'm sure!)
Chelle, it will be fun to see how those seedlings progress!
Veronica, Glad your 'Black & Blue' returned after all! You are so right about the new growth sometimes coming up in a circle around the old plant; mine has done that, too! It reminds me of a mushroom "fairy ring." Perhaps, in the case of the Salvia, it should be called a "hummingbird ring" since those are the magical, winged creatures that like to frolic about them.
Karen, I'm sorry about your Black-Eyed Susan vines.
They are actually perennials where they are native so I'd think they'd have the ability to regenerate from the roots. Since the rabbits left the stems, another thing you may want to try is rooting cuttings of them. Some of the "special" cultivars are propagated this way. I imagine they are pretty wilted by now, but you can try immersing them in a bucket of water and leaving them there until they rehydrate. Then, when they have perked up, you can make some stem cuttings. If it works, then you'll have even more Black-Eyed Susan vines than before. Gotta make lemonade, you know! (or maybe rabbit stew!
)
