If you look closely you'll see that it's infested with numerous small caterpillars. Not sure what they are other than larvae of a moth that lay eggs in immature buds. The larvae eat the insides of the buds, destroying or disfiguring the flowers, and crawl out through a tiny hole and at some point create that sort of webbing that is visible in your photos. I've probably got the mechanics all mixed up but I get them on salvia sometimes. Remove and destroy all infested flowers, watch buds and squish all that you can see. If an individual bud has a tiny hole, a caterpillar should be present. You could try an insecticidal soap, but not in the heat of the day.
Maybe someone else can actually identify this particular pest!
