That is Fulva Kwanza Flore Pleno . it has a triple layer of petals . It is still a species daylily like Ditch lily ( Fulva Europa)

And it is just as invasive. I can attest to that from experience.

I have this in my yard and love it. Very large blooms and very colorful. Mine are only 2 years old so I don't know how invasive they are but I've enjoyed mine.

Thanks for the ID! I know they can be invasive - but where I've planted them, down in the corner of my yard nearest the street, surrounding the street sign and stop sign - I don't really care if they spread :) I mean, if they start spreading more than about a 5 foot square maybe I'll start caring, but I'll just mow them over when I mow the grass.
