Maybe Gilbert Grape? :D I am probably a bad person for this, but I can't tell without a picture.

Sounds like it might be slug damage.

Get some sluggo or bug-getta. The slugs and snails will eat it to the ground and eventually kill it.

I not only get slug damage on some of my plants, but I also have problems with earwigs. They turn the leaves into lacey curtains. I recently put out cat food cans filled part way with vegetable oil, and I've captured hundreds. :)

For the slugs, I put beer in the cans, and bury them ground level.

Lacey curtains is a pretty good description of these salvia leaves. Maybe I will try both measures - slug defense and earwig defense. I wouldn't know an earwig if I saw one but I have certainly seen slugs in my garden before. Thanks to all for the advice!
