Larry, I have Purple Rain Dance, and it does have a couple of fans 10"-12" from the clump. I also have a few other named Daylilies that have one or two fans that are a ways from the clumps, but have never noticed one have a scape or divide into more fans. I have only been growing Daylilies for a few years, so perhaps I just haven't had them long enough. I also noticed that I am having this on several of my three-year-old seedlings this spring, I haven't looked to see if they are siblings yet.

It sends out long runners off the roots and can crop up quite a distance from the mother plant.

Hmmmm .... I have this one and it is one of my fastest growing. I might have to think about moving that one from my registered daylily raised bed and planting it somewhere else to give it plenty of room to spread. Sure don't want that one popping up or out-sourcing all the others in the raised bed. I recently acquired Midnight Affair as well.

Here are my runners.
They don't have much space so maybe they run for short distances.

1. I would like to know of any other named varieties that form plants from "runners", "rhizomes", or "stolons"?
2. Can just a piece of a "runner", "rhizome", or "stolon" grow a new plant.
I have personally dug up daylilies that were known to have "runner" type "roots" and had several plants pop up later in that area. So I am thinking that no part of a crown is necessary for this to happen.

A rhizome is an underground horizontal stem, a stolon goes along or above the soil surface. They are sometimes incorrectly used interchangeably. I have not seen a daylily produce a stolon, only rhizomes. Sometimes stolon and runner are used interchangeably also, but they are often differentiated. A strawberry stolon is often described as being a "runner", where the new plant only occurs at the very end. A stolon may produce several new plants along its length. They are also sometimes differentiated on the basis that a stolon can survive independently whereas a runner cannot.

But unless someone is seeing a daylily form these structures at or above the soil surface, stolon and runner are not applicable to daylilies and the underground stem is a rhizome. Not sure if that helps or not!

Yes a daylily rhizome can grow a new plant, or several new plants even without a piece of crown. A rhizome is not a root and daylily roots cannot grow new plants.

Here's a sequence of pictures I took some years ago showing a rhizome that had become detached from a crown. You'll probably need to click on the image to see the full sequence of development. The top image is a daylily rhizome that had detached from a crown, and the others show its later development into individual fans:

Great picture Sue! I'm understanding a bit better now. Apparently, many DLs have this behaviour, at least reading this post it seems that many of us find plants from rhizomes.

I sometimes find small plants a little ways from a large plant, but I always assumed it was a prolif that I stuck right next to the plant. or a small root left over from a former plan;. have to look closer. Interesting thread, I was trying to remember what salmon pagoda looks like as I know I had several. I also have some that I assume are runaway sprouts of ditch lily but maybe this is salmon pagoda? I also have Little Judy, which is a shorter, well mannered look like ditchlily variety. I might have some more that I purchased that look like ditch lily. Maybe I should plant all these questioned plants together so I can evaluate them more carefully! (Or maybe I should mark new plants more carefully?)

Maybe the important thing is the length of the "runner". Don't all daylilies send up new fans a short distance (inches) away?

Dig down very carefully around the base of a plant that you think is a "normal" plant and see if you find a root that would extend from the mother plant to the new plant several inches away (if you can find one). Then do the same with a plant that is four or five inches from the mother plant (one you feel sure is a rhizomatous plant) and follow the root from the mother plant to the new one. That will give you a better idea of how a rhizomatous plant spreads. Most plants do not spread by rhizomatous roots, some do and they are not aggressive with their spreading. Others want to take over the entire daylily bed.
