I planted the rhizomes last year end of July. Magic Happens and Kitty Kay from one seller and Lest We Forget from another seller. I've gotten more from each of those sellers at that time and so far, they seem okay.
Just a bit disappointing when trying to create a variety of color and this happens. I'll have to wait till July/August to replace with perhaps different ones but with the same color/characteristics.
