You're very welcome! Even us "oldies" need help with stuff too, so don't feel bad!
I was really surprised about how soon a seedling will grow those fatter roots. I had one that was about two inches tall, and it had those roots. They were small, but there was no doubt about what they were. That made me feel a lot more confident about weeding grass near the daylilies! But, I still question things like this, because even though I've grown daylilies for a long time, I'm never surprised at how much I still learn from others.
