Yea, Hi Buddy my BB rebloomed in the convention gardens in NM. So it only does so in a climate with a very long growing season.
My daughter grows IB Champagne Encore in norther Ohio. However, it grows so beautifully it has outgrown its bed with now no room for rebloom. It will have to be divided and some plants taken out & sent elsewhere.
around here in MA the rebloomer in gardens Is TB Immortality, although when I had IB I Bless, we also had fall bloom.
