Spiderwort Fading, Yellow Spots on Leaves

Q: What is killing my spiderwort?

A: I know the yellow leaf spots are worrisome but frankly your plant looks relatively normal for early May.

Spiderwort blooms freely in mid-spring but as the weather heats up, the foliage dies back. It may re-grow a bit in the fall and perhaps bloom some more then. It will almost certainly come back in this spot in the next spring.
