Daylily (Hemerocallis 'Subtle Knife')

I have had Subtle Knife at least 10 years. A beautiful flower that opens nicely and plenty of buds. Not a fast multiplier, but it has survived drought, intense heat, below 0 temps, and a guy driving into my yard and getting stuck. He spun all over my daylilies trying to get away before the cops came. IlLambertson's daylilies don't often do well for me, but this is a keeper.
