Grass Out Max (Clethodim Herbicide) is labeled to kill bermudagrass and safe to be used around liriope and lantana. It lists wirestem muhly as tolerant but not pink muhly, breeze grass or butterfly bush.
We would recommend contacting the Master Gardener with the Cooperative Extension office for recommendations for treating around those ornamentals.
Another option will be to spot treat with a non selective such as RoundUp QuickPro carefully spring the weed directly. This will not leach into the soil near desirable plants if applied carefully.
