Thank you for your response Deryl and Sooby.
@Sooby: it looked like normal growth until it didn't. I'm not sure if there was any delay of growth between the initial normal fan leaves and the start of the short ones growing from the center.
A bit more info:
I have about 200 daylily seedlings growing indoors under grow lights. All growing under the same conditions. This is the only one with this strange growth which I noticed the other day. Initially, it looked like all the other seedlings and had the long leaves (now the outer leaves) then started growing the short fans from the center.
I don't have the date this one sprouted but most of the seedlings sprouted in September and October. I planted one seed per cup or starter cell. This one was repotted in either late November or early December. This is when I didn't transfer the label when repotting three of them.
This is a pic of the indoor set up taken about a month ago of one of the shelving units. There are two three foot lights per shelf. These are grown in the basement where the temperature has remained in the 60s over the winter.
As the seedlings grew, the height of the space provided increased to accommodate the growth. You can see that the seedlings are grown close together but not to the extent that any would be stretching for light. The seedlings on each shelf are generally the same size in terms of height and are on different shelves depending on how tall they are.
