Re: Re: REB: rebloom seedlings
iris@hort.net

Facilitative vernalization rebloom referrers to those that rebloom only in ag zone 8 and 9. Sometimes called Coastal rebloomers, California rebloomers or warm climate rebloomers.

Oxmoor Hills has rebloom reported in zones 5, 6 & 7 but not 8 or 9

Gates of Heaven has rebloom reported in zones 6 and 7 but not reported in zone 8 or 9

So neither is a FZ iris, I would expect rebloom in first generation as both has FC genes plus need to have good secondary rebloom genes as they do rebloom. in zones 6 and 7.

Tea Leaves is reported rebloom in zones 5,6,7,8 &9. Not a FZ plant. So will be expected to produce rebloom in first generation (for zones 6 and 7) when crossed to something with good secondary characteristics.

Both of these are examples of the crosses I would recomend for getting rebloom. And ones that should give lots of seedlings that survive and that you can choose from.

Linda, this is not a criticism of your breeding program. I'm trying to give people information that helps develop a program to produce rebloomers using the most productive choices. And that is using rebloomers in your climate that are reliable and consistent with the iris that in your climate that have best secondary rebloom characteristics.

Stay away from the seductive but false reasoning that FZ (warm climate only rebloomers) bred to good reliable rebloomers in your climate will lead to rebloomers with characteristics of warm climate bloomers. It can be done, but will take a lot of time and you will be much farther ahead using plants that do exceptionally well in your own garden, combining great rebloomers with strong growers with secondary rebloom characteristics.
