Really, that is what I've heard. :)
I first learned of it in JT with Dave Niswonger and in the Morris garden during the St. Louis convention. There are dwarf SPU and some hybridizers are even breeding modern versions (of course, now I can't think of who, but they've talked about them in the "Spuria News").
Here's the SIGNA page on I. graminea:
and here it is on the SIS site:
You really did find two SPUs.
Someday I'd like to grow it and see if I could get any crosses out of it, but I've been told that there are some ploidy issues in the SPU species realms.
