Re: HYB: more experiments...& question

Linda, 

I'll address the last question first.? The 1810 cross was a "pot" cross.? Crazy one at that.? The pod parent bloomed in a mum pot!? (yes, a mum pot)? I made the cross, while the pot sat at the edge of my carport.? It got early morning sun and was shaded for the rest of the day.? I watered the pot each day.? A little soil washed out each day and the pod finished off with about 3 inches of soil in the pot.? Matured 41 plants from 52 seed.? Thirty eight of them are 2nd year germinants.? Many have bloomed in the summer.? (Maybe this is the way to go!? <vbg>)

Also, set a fall pod years ago which I dug and finished off in a?unheated room in the house.? One parent from Another Bridge & Theme Master. ?

Guess I'm still a little confused about your definitions of rebloom classes!? 

Most rebloomers, but not all, bloom early in the spring.? Summer bloomers, belong to the group known as multiple bloomers, formerly everbloomers or continuous bloomers.? (Immortality, etc.)??By their defintion, do not normally bloom in the late fall, although some?can do so in addition to their summer bloom.? 

Cycle rebloomers NEVER bloom in the summer, but come along in the fall.? It is my understanding that they do not contain the genes or triggers that allow summer bloom.? When we get the early fall freezes, Oct 15 last year, most of these do not make it.? I've not grown all cycle rebloomers, and I've never gardened in zones 7-9, so I'm speaking of rebloomers as I know them in my garden.? Thus the name cycle.? Harvest of Memories is one that comes to mind.? 

The fact that multiple bloomers (everbloomers/continuous bloomers) can bloom at any time is what leads me to believe they & the sporadics are of the same class, with the multiple bloomers having less demanding conditions/triggers.? Neither have a set time to bloom, as do the cycle rebloomers.? 

What do we get when we mix the multiple rebloomers with the cycle rebloomers???Can we breed irises that bloom earlier in the fall (when we want them) without them blooming (sometimes) in the heat of summer when we don't want them?? 

Just more questions!? 




<<If surviving very early spring/very late fall blooming seedlings are the 'norm' from "summer" rebloomers, I can't normally use them for further breeding because they will nearly always be frozen out here.?
?
Now that I know I can keep many climate sensitive store bought cultivars growing well enough in pots to at least give me one bloom season's worth of viable pollen, maybe I can set pods on some of these very early/very late rebloom seedlings if I grow them in pots.?
?
Have any of you successfully set pods on potted irises? Did they mature normally and produce viable seeds??>>

Starting to feel like I'm talking to myself here (again), but some of you have said you enjoy my ramblings, so here's the latest idea:?
?
If surviving very early spring/very late fall blooming seedlings are the 'norm' from "summer" rebloomers, I can't normally use them for further breeding because they will nearly always be frozen out here.?
?
Now that I know I can keep many climate sensitive store bought cultivars growing well enough in pots to at least give me one bloom season's worth of viable pollen, maybe I can set pods on some of these very early/very late rebloom seedlings if I grow them in pots.?
?

?
The one time I tried this was in the fall (December, I think) and while it did set a pod, the pod didn't mature normally, and the few seeds it contained didn't germinate.?
?
Some of my seedlings don't like pot culture, but some seem to be thriving, a few that I didn't get around to planting back in the ground year before last are putting up bloomstalks.?
?
If this approach will work, I will probably put together some kind of unheated semi-permanent plastic or Reemay covered outbuilding to grow the extra-early bloomers in.?
?
Not enough room in the house, plus it's too much work dragging pots around.?
?
Light frost last night that didn't last long, but tonight may be worse.?
