A few hybridizers are working on this trait in TB rebloomers. Constantly searching for irises that bloom in the summer. <<FB and Like other traits it is stronger in some irises than others. Chuck, how many seedlings did you bloom from Forever Blue x Immortality?

Iris. Thus they bloom in spring and again in fall when the lenght of daylight hours match the trigger daylenght in spring (for rebloomers). Forever Blue and a number of it's children don't need that trigger, but bloom whenever a rhizome gets lare enough to support a bloom stalk. Most SDB rebloomers rebloom her very late in Fall, just before killing frost. This reflects daylight hours that trigers spring bloom. FB and its children bloom when ever, and thus rebloom in very cold regions. and troughout Summer.

I've never heard that term before. Billy irischapman@ Here is a reblooming seedling from Forever Blue X Victoria Falls. It is an IB and is a regular rebloomer (not a daylight independent) . I keep trying to breed with it , hoping to get the daylight independent genes into the TB. Chuck Chapman ____________ More new features than ever. Check out the new AIM(R) Mail ! - http://webmail. |
