I'd say you are 100% on Immortality, and 95% on Rebecca Anne. Immortality is SUPPOSED to be the "reblooming wonder", but last fall was the first time in about 15 years of growing it that it put up fall stalks for me! Just before the bud opens it has a decidedly blueish cast to it, almost making you think the flower will be sky blue, and then, suprise ! It's white !...Arlyn
