I have a specimen plumbago that was in full bloom and overnight appears to be dead. No flowers or leaves, just dried sticks of a plant.
Will it come back if I prune it or is it gone? I hate losing it if it will revive. Any reason this happened?

As far as to why, there are many, many things that can kill a plant. For as quickly as you describe it succumbing, I would lean towards a chemical herbicide. Sometimes if someone is using something like Roundup on a windy day, the overspray can hit unintended plants and kill them.
