Fwiw, MY "Immortality" has also never rebloomed. I think I read somewhere once that there was an imposter going around, so I am increasingly suspecting that maybe that is what we have.
The database says the real IMMORTALITY is only 30", which is a little short for me (for a TB). EMMA'S LAUGHTER is 33" and has proven itself to be a rebloomer here (I have another rhizome sending up a stalk), so I guess the supposed IMMORTALITY gets added to the purge list. (The currently annoying candelabra stalk on EMMA started out with another branch which bloomed and displayed beautifully, so I am hoping that this new stalk coming up will also give me some good blooms.) Bonus points for being (slightly, sweetly) fragrant...
... though I suppose I must point out that EMMA'S LAUGHTER hints at being a bicolor as it has some pale charteuse in the center of the falls. (I personally don't care (until something better comes along
), but if you insist on the purest white, that might make a difference to you.)
