I think I have solved my own mystery. Tonight I finished cleaning, weeding and preening Nursery Bed #2 -- where the not-Pep Rally bloomed. And once I got all the dead leaves and weeds out of there, I could see several plant tags that weren't visible before. And right there, where not-Pep Rally bloomed, was the plant ID tag for Cardinal Rule. Just checked our database, and I think they are close enough to consider it likely. May not matter -- it would appear that the Cardinal Rule rhizome bloomed and rotted. It would also appear that I've lost Volcanic Glow...............
To add to my other issues out there -- I have mole runs in the raised beds, under the rhizomes. So -- some of the rhizomes are dangling in mid-air above a mole run, and other rhizomes have sunk down into the mole runs.
Just shoot me now.............
