I have had Lullaby Baby in partial shade since I planted it in 2011. I planted 25 fans, and pretty much left them alone. I lost some over the years, yet still have some nice clumps. I dug up a clump this spring and got at least 7 or 8 fans (why didn't I keep count? :doh:)
Lullaby Baby blooms pale pink in my garden and has lovely blooms, small and nicely formed. It opens/stays upright but the scapes sometimes lean. I frequently pick off bee pods and have used it one cross (yeah, I'm really that new to this...)
Last summer, July... Blurry, but shows the pale pink color nicely. I might have another pic on the laptop. More pix soon (clump shot). Too dark to photograph tonight.
Lullaby Baby, warts and all so far this spring.
