I was just out pulling some dead leaves, and to my surprise I found a rebloom scape on 'Tuscawilla Tranquility', with a bloom on it! (The poor bloom was hardly open - it's been hot and dry here, but still, I thought that was amazing, given that I don't recall ever having seen rebloom on it here before (possibly because the deer kept eating it). I'll have to give it a little extra water.)
THEN, I found a rebloom scape coming up on 'Newberry White Dove'! I had forgotten that it reblooms some years (it is not reliable here). There is only the one rebloom scape, but still....
Since both are in the dry ground and not in a pot, I might take a chance and re-fertilize both of these... maybe I can get some more rebloom scapes?
