Dictamnus
The burning bush, as known from the Book of Exodus, may or may not refer to this genus, as its natural range, from Western Europe, through the Middle East and all the way to Eastern Asia doesn't match (although its close) with the events in the bible. However, the plant is so full of volatile oils, that it is possible for the plant, under the right, hot conditions! Its not happened here at Beth's, but we do grow this is the hottest and driest part of our garden, where it thrives.
