I have had Lullaby Baby since 2019, when I bought three large plants from Oakes Daylilies. They all bloomed that first season, and I was charmed by the pale peachy-pink, diamond-dusted blooms (which I have been unable to capture in a photo). They did suffer from root competition where I had planted them, so I moved them to a different bed in the fall of 2020, and since then they have taken off. They have all increased significantly and probably should be divided soon. Lullaby Baby typically blooms in May here.
I am sorry to read that Avedon's Lullaby Baby developed rust. Mine have not shown any rust so far, and here it is endemic. I must have different strains of rust here. I always enjoy Lullaby Baby and will keep it.
