The blooms of my lantana are turning black. What could be causing this?

This could be a fungus disease.
Check the soil moisture levels. Soil should dry out between waterings.
Make sure there is air flow around the plant.
I would prune away the black plant material.
You can treat the plant with Neem Oil as is works both as a pesticide and fungicide.
