<<your [tetraploid] Tall Beardeds that summer bloom... are they Fall
rebloomers too?>>

Hi Tom,
It's really hard to tell exactly what a plant is capable of doing during the first few years due to the limited number of rhizomes. I've known that Summer Radiance can and often will summer bloom, usually early July, since it's first summer. It has never fall bloomed for me, but recent reports indicate it fall blooms in some areas like VA & NE.
I have three seedlings from Blatant x All Revved UP which have stalks, now. Two are plicata and one is a purple self. ARU has bloomed spring through frost in the home garden. (here) These stalks are too short to suit me and the blooms a bit bunched, a trait I'm trying to breed out. However, these are in a bed which has been seriously neglected.
I've been following your wonderful series of photos with summer bloom. It is exciting! You've not divided this clump since maiden bloom? 

Unfortunately, my MTB breeding will be rather limited.

Betty

Hi Betty,
I haven't worked with Welch's Reward, so I couldn't say for sure. But I can't imagine that (with your experience) you're doing something wrong. I'd bet that they've got some required dormancy breaking condition that just didn't quite get 
met - and that if you keep them around another year, you'll get some
germinations.
I'm glad to see that you're working with diploids, because I remember that you also have an interest in summer bloom. I've got a diploid MTB seedling, that I've been recently posting pictures of on the Iris-Photos forum, that has been blooming (as a second flush) all through June and now into July. Its first [and main] flush started in early May. I'm in Maryland, and my very latest bearded to bloom has always been Iris rudskyi which blooms in early June. There are usually just a few stragglers that are still around when rudskyi blooms. Rudskyi has been done for several weeks now. So it's pretty weird for me to be having an iris in bloom right now. And this seedling has had, I think, 6 or 7 of these repeat stalks on a basketball sized clump, so it'd be hard to just write it off as a fluke (like I could for its sister which has just one repeat stalk - in bloom right now too). Both of these seedlings have rebloomed in the Fall for 
three years now.
So... your [tetraploid] Tall Beardeds that summer bloom... are they Fall rebloomers too? I'm thinking that these might just be what would have been Fall rebloom stalks but that they got triggered early. So maybe I won't get as much Fall rebloom on this seedling now. Whatever the case, I think that there's 
potential being demonstrated for an all-summer-blooming iris.
Wouldn't that be cool!
Best of luck to ya, with your Welch's Reward X Consummation seeds, and others. 
Tom
