I'm submitting my nomination for ugliest Jack Frost specimen.
Believe it or not, he was beautiful all spring / summer until about 2 wks ago.
Then he threw in the towel.
He's just in a few hours of morning sun, otherwise shaded all day.
I've always presumed they can't take the heat / humidity of our late summers.
They reliably bounce back in the spring.
And they're so nice in the spring, I put up with the late summer swoon.

Should I take off the wilted / brown leaves? Or just leave it be?
It's got some fresh green growth in the middle.
