I agree with both Corey and Steve ........ if Judy says they have instant rebloom, they do for her and will have the genetics for that trait.
Not the color you are interested in, but this beauty has instant rebloom even in my cold zone 5b (sometimes a 5a ... even a half hour south of me is usually 2 weeks ahead)
"A Lot Like Love" (Davisson 2013) Pink variable crispate with gentle ruffling, lighter pink midribs, and a wide cream yellow throat that that is Diamond dusted. Blooms have waxy, rainproof substance and fine white edges. Scapes are 34" tall with wide spaced 3 way branching, 20 buds, plus an additional 12 buds on rebloom scapes that come on immediately. Rebloom flowers are larger at 10" with twisting tepals and sepals that often quill (See photo). Extended blooms. A splashy season extender because it starts mid-late season and is one of the last cultivars still blooming in late September. Easily fertile both ways.
Maybe try it with something closer to the color you want .......... this beauty blooms for a very long time for me. (Mama Drama's color is fantastic ! Would have to make nice babies with A Lot Like Love ... what dreams are made of.)
