Does anyone know what's wrong with my gaura? We planted this gaura (and several others) in April. All the others look perfect but this one is small and scraggly with weird tiny leaves. It's been that way for months. We have a lantana next to this gaura and now it recently it began growing tiny leaves so I'm worried it's something contagious.

I had some problems with Lantana this summer that looked a lot like this. I treated with Bayer Fruit and Vegetable Insect Control and they look better. Not 100%, but better. I think they might have Chilli Thrips.
