Thanks for that experiment Jan. I am more suspicious now since the clump is in low, boggy land that is a potential runoff area about 150 feet downhill from a road verge. Hemerocallis is reputed to be resistant to herbicides due to the waxy coating on the mature foliage, but if the herbicide is in the groundwater its a different exposure mode, of course. If they exhibit the same behavior this year, I'll take pictures and move a few of the plants to my garden where there are no herbicides. That experiment will be a bit longer than yours, unfortunately.
