Below is a link to a site showing how to divide daylilies. The pic with the hose shows a double fan. The pic where they are planting it in a pot appears to be a single fan.

Hope this helps

Here is a link that might be useful: Dividing daylilies

Thanks!! That was a great link!!

When a seller refers to a fan they should refer to a blooming size fan unless they clearly state otherwise. However, when refering to more than three fans they normally mean any independent piece of daylily which when planted will grow into a new individual plant.

I have received daylilies so small I could blow the fan through a straw but that is not typical. Plants coming from the south have a much longer growing season so the fans coming from the south are typically much larger than fans coming from the north. It is not fair to expect as large a fan or as many fans from a northern grower -- their season is just too much shorter.
