Before I cleaned things up, I thought I'd try to get photos of those with rebloom scapes. I'm not clear on what constitutes instant rebloom, but these scapes seem to have arrived quickly.
Lillian's Vapor Trail. In a perfect world there would have been one more initial scape and one more rebloom scape, but hail got the first and either grasshoppers or katydids got the latter. I didn't deadhead prior to the photo. The bloom today is on an initial scape, the dead blooms from yesterday are from both.
Buddy's Wild and Wonderful. The first scape to finish is the one turning brown, but the last three blooms on the initial scapes are blooming today. You can see the four new scapes aren't too far away from bloom. The scape showing on the right is another DL. All the new scapes are showing under the blooms.
Dreams Come Through. One more bud to go on the original scape and you can see the stage of the rebloom stalk for comparison.
Marked By Lydia. The five visible original scapes (one more was taken out by hail) are turning brown. There are only two rebloom scapes so far, so I guess not all are going to rebloom.
