That looks like the species hermerocallis "fulva" commonly known as ditch lilies. In other words it's the hemerocallis that all of the others were bred from. It is a wild flower here in the states and every part of it is edible! They can take over your world so be sure to keep them in check. I have them in several places in my yard but divide and share them when they get too big, usually every other year.

Enjoy!

I've heard them called "outhouse lilies", it can become very invasive.

They will literally grow like weeds but are very pretty ones!

That is what I was leaning twards. The two fans I transplanted (third season now) are HUGE! I really like them, but they dwarf all other daylilies I've seen. These guys are so stinking macho. The electric guy stepped them flat to the ground, they popped back up a wk later. I got some overspray weed killer on them, doesn't bother them at all. I dug up some clumps to thin them out and just tossed them into a corner of the yard on top the lawn, the darn thing is bare rooted and is budding out!! I get a kick outta these. Let them spread!

Its good to have these if you have a dh like mine. He is always wanting to eat our special daylily flowers so its good to send him to the ditch lilies.

Yep! that our beloved *ditch* lily. I think it grows wild in every state. I had them in Michigan and I have them in Tennessee. I love them also. I have a Double orange day lily which is really beautiful and they multiply just like the *ditch* lilies. Probably a cousin!! lol

I dislike the name 'ditch lilies' and always refer to them are 'road side' daylilies. It speak a little kinder to the parent of all daylilies. They are the first to bloom for me so I keep a few just to remind myself that the great display is finally coming.

Technically they are Tawny daylilies. I don't like calling them 'ditch' either. To me (no offence intended) stella de oro's are so commonly boaring around here. That's my idea of something to throw in the ditch.
