I don't think your noid is "yellow enough" to be Truly Yours. Noid appears to me to be more "cream" in color, and, somewhat older in" form"( falls appear a little too long and floppy). My guess would be an iris from the 30's. Parthenon, or,maybe Selene would be close. Not sure if those are in the Data Base. I wouldn't buy any test plants just yet! You're gonna' need lots more info for this one, as there were lots of creams, or "soft yellows ,off-whites",( or however you want to describe that color) from that era. That's just my opinion....Arlyn
