Great. I'm following the hybridizer. No pressure.
Fortunately, it has been a good plant for me, even though I have moved it twice now, continuing to try to put it in a better and better location. It is pretty white for me. It has a great history of coming back to rebloom for me later in the summer. It took last year off, but a lot of plants did because of, well, snow in April and drought in May.
Interestingly, I can't say it's my best Huben rebloomer. Magenta Kisses has bloomed continuously some summers, and always reblooms if it does take a week or so off. Accentuate the Green and But I Repeat Myself also rebloom at least as well. But then again, they have all been in a better locations. When Vanilla Stella settles in to it's new location, maybe it will give Magenta Kisses a run for its money.
