Here's another interesting site about species daylilies. It does look like your orange one is a ditch lily and the lighter one looks like Hem. fulva Linda, which it says is not as invasive as the orange ditch lily. I've always been a fan of the ditch lilies but don't have enough room for them to roam here. Your new bed will look great!
