I'm not sure if your comment that we are misunderstanding each other is aimed at me or at one of the others who have replied on the thread, but I don't think it makes much difference. I understand you, and from the other responses, so does everybody else. As I look back at some earlier posts, I see that my phone autocorrected "If you click the link . . ." to "Of you click the link . . ." so if that's the cause of the miscommunication, I apologize.
I don't think anybody else is surprised by this. It's common practice for a seed company to come up with a brand for a bag of seeds and change what goes into the bag based on availability, locale, or some other reason or reasons known only to them. This is nothing new. Go to Walmart and find a bag of Scotts Sun and Shade. Take a picture of the part of the labels that shows the seed composition. Then go to Lowes and do the same, then to Home Depot. Maybe even check a couple of labels at each store. If they're all the same, wait and check again next year.I’m just ranting now, but I’m as surprised by this as anybody else may be
Jacklin has two (at least) cultivars of TTTF seeds that they claim are rhizomatous (I say claim, because I've seen other claims of rhizomatous tall fescue in the past and have been disappointed; but that was years ago, and it's possible that selective breeding has really come through). They're marketing these seeds primarily to sod growers, and selling them as NoNet, meaning that there's no need to use nylon netting as a stabilizer until the sod is formed, since the fescue will spread to form sod.
So if you buy NoNet, you're getting Flame and/or Sunlight.
Are you sure that Sunlight and Flame are cultivars that are already available? I've done some cursory searches and haven't found them in anything but references to the Jacklin NoNet product. I looked at the most recent NTEP report I could find and didn't see either listed, but there were several entries for Jacklin that were numbered, rather than named (like JS 818) and I'd imagine that two of those were named Flame and Sunlight.
