Hello jacktree and welcome to the forum.

I am sure not an expert, just been gardning a long time and my advice would be this: When the weather cools a bit get that shovel out and start seperating those huge clumps to smaller sizes. What part of the country are you in. I like to seperate in early fall, gives the new roots time to get going before winter. Don't forget to give'em plenty of water. Sounds like you have the old daylily everyone calls the "ditch lily". If it is don't worry, you can't kill it.

There are many expert gardners on here that will give you some good advice so good luck, looks like you'll have plenty to do this fall.

Sounds to me like a clump of ditch lilies also. If you plan to add any more daylilies to your collection (the hybrids don't droop) just be sure to not plant new ones anywhere near those you already have!

Thanks for the info.They probably are 'ditch lillies' they were put in long time ago by much earlier owners of the house, and are located in a natural drainage swale, they cover the top of the embankment the sides and bottom of the swale. I'm located in the Great Lakes region, here these type of lilies are often referred to as 'Tiger Lilies'. They are thick, and it's a big patch of them if I ever thin them out. It's also been extra dry here the last month, but we're supposed to have several days of rain, so maybe that will perk them up.

Please identify the "Ditch Lilly" by name for me. I may have some from the above description. We are in a drought and all of my lillies look dreadful - some worse then others.
I also have a very, very steep bank - I may want to move the daylillies mostly "Ice Carnival" and "Joan Senior" & replace w/ the Ditch Lilllies. This bank is impossible to maintain - need erosion control and something that will compete with the crown vetch - that somehow got there. Any guidance is appreciated - even if it is to say DO NOT PLANT THE DITCH LILLIES! I have a nice yard and gardens & this hill is beating me!
Thank you.

Hemerocallis fulva is a single orange colored wild daylily. The mother of many of the daylilies that we have today. Great for naturalizing or for erosion control. Another one is hemerocallis kwanso called a double ditch lily (actually a triple). Don't buy them if you can avoid it. The grow wild along side of roads. If they are on a persons property, stop and ask. They multiply so fast that most people don't mind sharing. If you must buy them go to a site that sells them in bulk $1 - $2 each.

Thank you Tom. I do have the Double Ditch you pictured - and it has multiplied like crazy. I have spread it into my beds! It was originally given to me from my DH uncle from PA. I thought he called it a Ruffled daylilly. He is a farmer from way, way back - has an incredible green thumb and an absolutely gorgeous yard. He started collecting Daylillies about 10 yrs ago - seeking out particular ones. He is retired and has the time (and love) to do this! I guess I will wait until next spring to ID these and start moving them onto that dreaded hillside. I actually think of this particular "Ruffled" as special - just because he gave it to me - and point it out to my DH each year!! Thanks for the picture.

Ditch lilies are wonderful for a hillside or as ground cover where nothing else will grow. To the original poster: Once they are through blooming, just mow them to the ground. The new growth won't flop.

Mow them to the ground - true for all daylilies? - usually mine don't look so horrible - this year the drought has caused them to flop and lay over - I tried to clean them up over the wkend, but they look so bad and sad laying on the ground. They were watered, but not enough - too hot also. What to do with them is what brought me here taday. Thanks for your time - I always learn so much from GW.

In the extreme stress of heat, I wouldn't mow down any daylilies other than the ditch lilies personally. They are laying down because they just plain don't want to be forced to do anything else. I would just let them be.
