Salvia nemorosa 'Marcus' and 'Carradonna' seeded out?
I have 3 'Marcus' and 7 'Carradonna' that were planted within a few feet of each other in my butterfly garden. Marcus is shorter, but the foliage is similar to Carradonna. Marcus has been in the garden since 2007 and Carradonna was planted in spring 2008.
I seem to have some "extras" that have magically appeared at the bottom of the slope (a very moist area over the winter where I never plant salvias). The foliage really looks like nemorosa. Or, a weed that's doing a great impersonation!
The only other salvias in that area are greggii and guaranitica 'Purple Majesty' and the foliage doesn't match these babies. Is it possible that nemorosa seeded out like that? I know I can wait and see the height/color, but is there another way to tell which salvia seedlings are growing? I'd like to move them to a more suitable location before they drown in the next big thunderstorm as they are now growing in the rain garden.
