The name Lullaby Baby seems like a misrepresentation as it's not really much of a baby, but it has always struck me as having architecturally lovely, symmetrical, blue-green fans of leaves. Add nice branching and good increase and I'll keep it forever, even though I wish it had rebloom. For a dip, it has amazing plant presence before the clump gets crowded and the fan size diminishes.
I am pleased to have Carol Van Sciver as well (also a whitish dip, but more recent) and really look forward to
her strutting her branching, chartreuse stuff more fully in 2022. Paul Owen remarked that her children are easily identified by their rich green color in the greenhouse while still young seedlings.
A daylily plant doesn't have to have have different colors or be variegated to make a statement. Good, strong plant habit can be attractive too.
Lullaby Baby is always more than 19"" here. I don't have a good pic of the fans.
